From Duramax diesels to Hemi V8s, the right truck exhaust manifolds fix leaks and ticking without breaking your budget or your back during installation.
Our Picks at a Glance
How To Choose The Best Truck Exhaust Manifolds
A cracked manifold announces itself with a ticking or tapping that grows louder as the engine warms. To pick the right replacement, you need to match your engine family, choose between cast iron and stainless steel, and confirm which bolts and gaskets come in the box.
Cast Iron vs. Stainless Steel
Cast iron manifolds are the factory standard because they handle extreme heat and resist cracking better than cheap stainless. Ductile iron takes that a step further—it flexes slightly under thermal stress, which is exactly what prevents the warping that leads to leaks.
Kit Contents Matter
Some kits include gaskets, studs, and nuts, while others only ship the manifold itself. A complete kit saves a parts run, but many buyers replace the included gaskets and bolts with higher-quality hardware—budget for that swap.
Fitment Is Everything
Confirm the exact years, engine codes, and body styles before ordering. A single digit difference in engine designation can mean a manifold that doesn’t align with your bolt holes, and nobody wants to wrestle a 13-pound chunk of iron into place twice.

In‑Depth Reviews
1. Dorman 674-522 Driver Side Exhaust Manifold Kit
Our pick — 4.5★ from 500+ verified ratings; the strongest balance of quality and price.
The GM 5.3 fix that comes with everything but the wrench.
Owners describe this as the cure for the notorious GM 5.3 ticking, with buyers reporting it fits like the factory piece and the heat shield bolts straight on. The material is ductile iron—not brittle cast—which is exactly what prevents the warping and cracking that killed your original unit. At 13 pounds, it’s a solid, hefty piece that feels like a real repair part, not a cheap stamping.
The kit ships complete with the manifold, manifold gasket, flange gasket, 3 studs, and 3 nuts, so you’re not making a second parts run mid-project. Buyers specifically praise the design gaps between bolt heads that allow for flexing—a detail that stops the bolt-snapping cycle common on the GM 5.3 platform. It’s designed and tested in the United States, which shows in the precise casting finish reviewers call out.
There is one honest fitment warning that comes up repeatedly: on some 2003 GMC Yukon models, the manifold may interfere with the coolant temp sensor and require trimming. Buyers report this is a manageable tweak, but it’s worth knowing before you tear everything down.
What Wins People Over
- Ductile iron resists the warping that plagues cheap stainless
- Complete kit: gasket, flange gasket, studs, and nuts included
- Perfect fit on both ends, heat shield ready
Fitment Caveat
- May require trimming near the coolant temp sensor on some Yukon models
- Heavy at 13 pounds—awkward to hold while aligning bolts
The pick for most: If you own a GM 5.3 and want a ticking cure with zero extra parts shopping, this kit is the complete answer.
Think twice if: You’re working on a tight sensor clearance and can’t tolerate any trimming—this one may need a little massaging.
2. GXP Updated Driver Side Exhaust Manifold
Un-crushes your Duramax exhaust flow without the dealer markup.
If you drive a 2001-2016 Chevy or GMC 6.6L Duramax, the factory manifold on early trucks is literally crushed to clear the chassis—restricting flow from day one. This GXP replacement eliminates that crushed design entirely, and at 11.14 pounds it’s noticeably lighter than the Dorman kit above, a 17% gap you’ll feel when you’re holding it in one hand. It’s a factory-style replacement on later LML trucks, and a high-flow upgrade on the earlier LB7 through LMM generations.
Owners mention the fit is perfect and the swap is straightforward if you remove the inner fender, drop the hot side intercooler pipe, and lower the intermediate steering shaft. The manifold has been in trucks for months with zero issues. GM OE cross-references (12624684, 12637647, 97224587) confirm it is a true replacement part, and the 1-year warranty covers you if anything goes wrong.
The included bolts are the weak link—buyers describe them as the wrong size, thread, and type, essentially useless for the job. You’ll want to reuse factory hardware or buy quality studs; the manifold itself is the value here, not the hardware.
The honest read: The casting is solid and the flow improvement is real, but plan to reuse your factory fasteners.
Reach for this if: You own a 2001-2010 Duramax and want to ditch the crushed factory manifold for better flow.
Look elsewhere if: You expect bolt-in hardware—the included bolts are essentially unusable, so budget for quality fasteners.
3. A-Premium Right Exhaust Manifold Kit
The Hemi tick silencer for Ram 5.7L and 6.4L trucks.
Ram Hemi owners know the “Hemi tick”—that rhythmic tapping that’s almost always a broken exhaust manifold bolt. This A-Premium kit is the direct fix, with buyers reporting it cured their tick completely. The compatibility list is broad: Ram 1500 2013-2018, 2500 and 3500 through 2020, covering both the 5.7L and 6.4L V8s including the 1500 Classic up to 2024.
The kit includes the cast iron manifold, inlet gasket, 2 bolts, and 2 nuts, plus a heat shield. Cast iron construction gives high-temperature resistance and stable performance, and the reference number 674-685 cross-references the factory part. Fit is the standout quality here—the most-discussed aspect in owner feedback is how closely it matches OEM fitment, installing without hassle at a shop.
One recurring note: the heat shield alignment can be fiddly, and some owners found the included hardware marginal. If your broken bolts are seized in the head, budget for extraction tools—that’s the real work on any Hemi manifold job, not the manifold itself.
What owners rave about: The fit is the thing—it matches OEM geometry so closely that an experienced shop installed it without drama.
Best for: Ram 5.7L and 6.4L owners chasing that ticking sound with a bolt-on replacement.
A caveat: Heat shield alignment takes patience—line it up before torquing anything down.
4. JDMSPEED Stainless Steel Exhaust Manifold
A stainless upgrade for the Jeep 4.0L that outlasts the factory casting.
If you own a 1991-1999 Cherokee, Wrangler, or Grand Cherokee with the 4.0L inline-six, this JDMSPEED manifold is a direct bolt-in replacement. The key upgrade: the pipes are stainless steel, while the flex joints and flange stay standard steel to allow natural thermal expansion. That split design is why it survives the heat cycles that crack factory manifolds—the flex bellows absorb the movement.
Fit is the dominant theme in owner feedback, with the most-discussed aspect being how well it lines up on 98 Cherokees and 99 TJs. The interior is smooth for better flow at high engine speeds, and customers note a softer exhaust note for a more comfortable ride. It replaces factory part numbers 33007072, 4883385, and 674-196, covering Cherokee, Comanche, Grand Cherokee, and Wrangler applications.
The honest trade-offs: the included gasket and bolts are weak, and most owners replace them with Fel-Pro gaskets and better hardware immediately. Some installations require a small trim on the intake manifold at cylinder #3, and buyers recommend re-torquing after about 200 miles. Durability feedback is mixed—some report cracks after 8+ months, though many more report leak-free operation.
The Value Story
- Stainless pipes resist the cracking that kills factory cast manifolds
- Flex bellows absorb thermal expansion naturally
- Fits Cherokee, Grand Cherokee, Wrangler, and Comanche 4.0L
Plan For
- Replace the included gasket with a quality Fel-Pro unit
- Possible intake manifold trim at cylinder #3
- Re-torque after 200 miles for a lasting seal
Who it’s for: Jeep 4.0L owners who want stainless durability without a header install.
Who should pass: Anyone who wants a true bolt-in with zero tweaks—this one benefits from better gaskets and a little patience.
5. Partsflow Left and Right Exhaust Manifold Set
Both banks covered in one box for the GMT400 generation.
This is a rarity in the manifold world: a set that includes both the left and right manifolds with heat shields, so you can refresh the whole exhaust system in one go. The 30.8-pound package tells you these are substantial cast iron pieces, not lightweight sheet metal. It’s aimed squarely at the 1988-1995 Chevrolet and GMC C/K-series trucks, plus Suburbans, Yukons, and Tahoes through 1995.
Reviewers point out the fit is genuinely bolt-on—”fits my 92 chevy like a glove” is the recurring sentiment, with everything needed included in the box. The cast iron construction matches factory spec, and the OEM replacement numbers (674-156, 674-157, 10045315, 14093658, 14102016) confirm correct cross-referencing for the TBI-era small blocks. A one-year warranty backs the purchase.
The catch is the lack of drama: there’s no performance gain here, just a faithful factory-style replacement that restores a leak-free exhaust. If your old manifolds are cracked or warped, this restores proper backpressure and kills the exhaust smell without any fitment surprises.
The simple truth: Owners call it high quality with everything included—a straight swap that fits like factory.
Pick this if: You want both sides replaced at once on an OBS Chevy or GMC and value simplicity over performance.
Not for: Anyone looking for a stainless or high-flow upgrade—this is factory-spec cast iron through and through.
6. Certified Automotive LS Style Headers
Mandrel-bent 304 stainless that frees the LS’s breathing.
Mandrel bending means the tubes keep a consistent diameter through every curve—no pinched spots to choke flow—which boosts exhaust flow and throttle response. The 304 stainless construction resists heat and corrosion far better than mild steel.
The 3/8″ thick laser-cut flanges are designed to seal leak-free against the cylinder heads even under extreme heat, and the round polished finish adds visual appeal under the hood. Buyers who got a good piece report the fit is perfect, the welds look good, and after four months there are no leaks and minimal discoloration even in northeast winter driving. The polished color develops a nice patina after a week of driving.
Here’s where you need to be careful: this one has real fitment variance. Some buyers received units requiring work—bolts with heads too thin for a socket, flanges that needed alignment to stop leaks, and in one case a flange with improper welding. It’s also not CARB approved, so California buyers should check local emissions rules before ordering. The performance gains are real, but fitment varies between units—a gamble at a price below premium brands.
Performance Upside
- 1-5/8″ mandrel-bent tubes boost flow over stock
- 304 stainless resists corrosion and heat
- 3/8″ thick flanges for a solid seal
Honest Risks
- Fit and flange quality vary between units
- Not CARB approved—California buyers beware
- Included hardware is weak; plan to upgrade bolts
The performance pick: If you want real flow gains on an LS truck and can handle some fitment fuss, this delivers.
skip it if: You need a guaranteed leak-free install or live in California—the fitment lottery and emissions status are real hurdles.
7. BD Diesel Exhaust Manifold Set Ford F-150 3.5L EcoBoost
The EcoBoost manifold set that uses every possible stud.
For the 2011-2016 Ford F-150 3.5L EcoBoost, this BD Diesel set is the definitive fix for the cracking manifold problem that plagues these turbos. The machined cast construction is a clear step up from the factory piece, and the design uses more fasteners than the stock setup—a key detail that distributes stress and prevents the bolt fatigue that causes failures. At 19.36 pounds, it’s a serious hunk of metal built for the long haul.
Shoppers say the truck runs better than ever after the swap, with the kit including everything needed for installation. The clean gasket surface requires no modifications for fitment, though buyers recommend chasing the threaded holes before stud install. The factory manifold removal is the hard part—the right side is notoriously tight—but the BD kit’s clear instructions and quality castings make the replacement straightforward.
The recurring owner advice is to read the instructions first and consider the BD install kit, which includes the proper studs and upgraded hardware. One honest note: if you’re removing the turbos anyway, replace the coolant lines proactively—they can leak after being disturbed. It’s a premium-priced piece, but for EcoBoost owners tired of repeat failures, it’s the last manifold they’ll buy.
Why It’s The Fix
- Uses more bolts than OEM to prevent fatigue failures
- Machined cast quality with zero-mod fitment
- Complete kit with everything needed
Install Notes
- Factory removal is brutal—budget time and a stud extractor
- Consider the BD install kit and replacing coolant lines proactively
The definitive EcoBoost fix: Buyers report trucks running better than ever with zero fitment mods.
Be prepared: The old manifold removal is the real job—this kit makes the replacement side easy.
8. BD Diesel Exhaust Manifold Kit Dodge/Ram 5.7L Hemi
The buy-once Hemi manifold that kills the tick for good.
The Hemi tick is a war of attrition: factory manifolds warp, bolts snap, and you are back under the truck in a few years. This BD Diesel kit ends that cycle with high-silicon ductile iron construction and significantly more ribbed material than the OEM design—buyers describe it as about 1.5x the weight of the factory piece, and that mass is precisely what prevents warping. It fits the Dodge/Ram 1500, 2500, and 3500 from 2009-2022 with the 5.7L Hemi, though not the 2019+ DT body style.
The kit includes longer fasteners with spacers plus all gaskets and fasteners, and owners consistently praise the fit and finish as excellent. The most-discussed aspect is quality, with durability a close second—this is the manifold you install when you’re tired of doing the job. Owners mention the tick is gone, the hardware is quality, and the included instructions are easy to follow.
The honest cost is twofold: it’s a premium piece, and the dipstick reinstall can be tricky on some models since there’s no stud to guide it—one owner fabricated their own. The other real-world headache is extraction: removing the factory broken bolts is the hardest part of any Hemi manifold job, so budget for a jig kit and quality cobalt bits.
The Long-Term Fix
- Ribbed ductile iron resists the warping that kills stock manifolds
- Complete kit: gaskets, longer fasteners, and spacers included
- Owners call the fit as good as OE with superior durability
Cost Reality
- Premium price, though buyers call it cheaper than a repeat OEM job
- Dipstick reinstall can be tricky without a guide stud
- Broken bolt extraction is still the real work
The buy-once answer: If you’ve done the Hemi manifold job before and don’t want to again, this heavier casting ends the cycle.
Who it’s not for: Budget-first shoppers or anyone with a 2019+ DT body Ram—it won’t fit.
9. BD Diesel Performance Pulse Exhaust Manifold
A beefy two-piece upgrade for the 5.9L Cummins that improves towing.
At 25 pounds, it’s the heaviest manifold here, and buyers describe its design as “beefy” compared to the cheaply cast stock piece. The two-piece construction replaces the factory manifold and adds performance flow, with the casting pre-drilled for two pyro probes so you can monitor exhaust temps.
Installation is straightforward, with no issues reported and excellent quality as the most-discussed aspect. Owners running 2005 Ram 2500s and 3500s confirm it fits nicely and performs well, with one noting a clear improvement in towing capability versus the OEM unit on an 06 Cummins. It replaces Cummins part numbers 3967995, 3943871, and 3943875, and the painted black exterior looks purposeful under the hood.
The honest caveats: this is a bare manifold—studs and gaskets are not included, which feels steep at this price point. Some owners also report the BD bolt kit is a disaster with mismatched spacers, so plan to use ARP studs to avoid the OEM bolt breakage and cracking problem. The manifold is excellent quality, but you’ll need to source your own fasteners.
The Performance Case
- Two-piece pulse design improves flow and towing performance
- Pre-drilled for two pyro probes
- Beefy 25-pound casting that outlasts the stock piece
The Fine Print
- No studs or gaskets included—buy ARP hardware separately
- BD’s own bolt kit has quality control issues
- Premium price for a bare manifold
The towing upgrade: Cummins customers note real performance gains on hills versus the factory manifold.
Budget for it: You’re buying the manifold, not a full kit—factor in quality studs and gaskets.
Understanding the Specs
Ductile Iron vs. Cast Iron
Ductile iron contains graphite nodules that let the metal flex slightly under heat, making it far more resistant to warping and cracking than standard cast iron. If you’re replacing a manifold that failed from warping, ductile iron is the upgrade. Standard cast iron matches factory spec but carries the same failure risk over time.
Kit Contents and Hardware
A “complete kit” usually includes the manifold, gaskets, and fasteners. But included hardware is often the weak point—many owners toss the supplied bolts and gaskets for quality brands. Check whether studs and gaskets are truly included, and budget for replacements if you’re chasing a leak-free seal.

Final Thoughts: The Verdict
For most truck owners, the truck exhaust manifolds winner is the Dorman 674-522 because ductile iron and a complete kit make it the most reliable, least-hassle fix for the ubiquitous GM 5.3 ticking problem. If you drive a Duramax and want to ditch the crushed factory manifold, grab the GXP DP0355 for a high-flow upgrade at a value price. And for Hemi owners who never want to do this job again, the heavier casting of the BD Diesel 1041463 is the one to reach for—it costs more upfront but ends the repeat-failure cycle for good.
