FAQs About HEMI Performance Parts
What performance parts does this collection cover for the HEMI?
Four departments: exhaust headers for the 2009-2018 Ram 1500 5.7 and the 2008-2010 Challenger 5.7, exhaust and driveline support hardware including the dual exhaust Y-pipe and heavy-duty U-joint, the HEMI-specific valve spring compressor tool for cam and spring work, and the oil catch can system with its Z-bracket for the 2011-2021 Charger, Challenger, and 300.
Together they address the platform's two famous problems, warped manifold tick and PCV oil ingestion, plus the hardware and tooling that keep performance builds together.
Why do 5.7 HEMI exhaust manifolds crack and break bolts?
Heat cycling is the culprit. The cast-iron manifold grows and shrinks across every drive cycle while the bolts hold it against the head, and eventually the casting warps and the stressed bolts fatigue and snap. The telltale symptom is the cold-start tick from the leaking joint, which fades as the metal expands and returns louder every winter.
Replacing the manifold with another manifold restarts the same clock. Headers with thick flanges distribute the clamp load evenly and tubular construction flexes with the heat instead of fighting it, which is why the header swap is the permanent answer owners arrive at eventually anyway.
What are the gains from headers on a 5.7 Ram 1500?
Better breathing at both ends of the rpm range. Smooth mandrel-bent primary tubes with dedicated per-cylinder runners cut backpressure and accelerate exhaust scavenging, which shows up as stronger midrange pull, more top-end power, and lower EGTs under heavy towing or high-rpm acceleration. The exhaust note improves as a bonus.
Honest expectations: headers are a supporting modification. They amplify what intake, tuning, and cam work deliver, and they fix the manifold failure for good. On a stock truck the gains are modest; on a built HEMI they are the difference the rest of the mods need to shine.
Long tube headers or manifold-replacement headers: which should I choose?
It comes down to goals and packaging. Long tubes, like our stainless set for the 2009-2018 Ram 1500 5.7, run longer primary tubes that maximize scavenging for top-end power, the choice for performance builds. Manifold-replacement headers package like the factory casting, install as a straightforward swap, and still end the warp-and-snap cycle with much better flow than cast iron.
Daily drivers fixing the tick usually take the manifold-replacement route; trucks and cars chasing power go long tube. Both are on this shelf for the Ram 1500, and the Challenger set covers the early LX cars.
Which years and models do these headers fit?
The Ram 1500 headers fit the 5.7 HEMI from 2009 through 2018, covering the fourth-generation trucks in both long tube and manifold-replacement designs. The Challenger header set fits the 2008-2010 Dodge Challenger 5.7, the early LX-platform cars.
The 2009-2018 Ram span includes the body update years, so confirm your build date if your truck sits at a transition, and our support team matches the correct set from your year and engine in minutes.
Do you have headers for the 6.4 HEMI?
Not in this collection. The header shelf here is 5.7-specific, for the Ram 1500 and the early Challenger, because that is where the manifold warp problem concentrated. The 6.4 coverage on this page runs through the catch can system with its Z-bracket for the 2011-2021 LX cars and the valve spring compressor tool, which serves the 6.4 alongside the 5.7, 6.1, and 6.2.
For 6.4 headers specifically, check with our 24/7 support before assuming either way, since catalog coverage expands with demand. We would rather tell you what is in stock than sell you the wrong set.
What does an oil catch can do for a HEMI?
It mounts inline with the PCV system and traps the fine oil mist that the crankcase ventilation would otherwise feed into the intake manifold. On a high-compression HEMI that mist is not harmless: it carbon-coats the intake valves and it enters the combustion chambers as oil, raising effective octane demand until the engine detonates and the knock sensors pull timing.
The catch can interrupts the chain before the intake, keeping the valves clean and the tune safe. The Z-bracket locates it cleanly in the 5.7 and 6.4 engine bays of the 2011-2021 Charger, Challenger, and 300, and draining it takes a minute at oil change time.
What is the valve spring compressor tool for?
Valve spring work without pulling the head. The POW352003 compressor is engineered for the tight clearances of Chrysler HEMI cylinder heads across the 5.7, 6.1, 6.2, and 6.4, compressing the springs, retainers, and seals on the vehicle so high-lift camshaft swaps and spring upgrades happen with the heads still bolted on.
Anyone who has tried generic spring compressors on a HEMI knows they do not fit the geometry, and improvising under a valve cover is how keepers end up in the oil pan. The right tool turns valvetrain work from a head-removal project into an in-place service.
What do the Y-pipe, U-joint, and active exhaust delete do?
They are the supporting cast that finishes HEMI exhaust and driveline work. The Y-pipe for the 2009-2019 Ram 1500 5.7 merges the dual exhaust banks with smooth transitions, equalizing backpressure between banks and smoothing the note instead of the turbulence a crushed adapter creates. The heavy-duty U-joint for the 2007-2018 Ram 3500 handles the shock loads tuned 5.7 and 6.7 trucks put through the driveline.
The active exhaust delete kit for 2015-present Dodge and Chrysler vehicles removes the factory valve system so flow never depends on a servo's mood. Bigger projects, sound and flow consistent, hardware that holds.
Are these HEMI parts street legal, and what is the warranty?
Most of this shelf is conventional performance and service hardware. Headers that retain the catalysts are a flow upgrade, and the catch can, Y-pipe, U-joint, and tooling are legal everywhere with no emissions implication. The active exhaust delete kit is the exception, sold for competition and closed-course off-road use only, and header installs that alter catalyst position fall under the same rules on emissions-equipped vehicles, so check your state's inspection before ordering.
Fitment is engine and year specific across the Ram 1500, Challenger, Charger, and Chrysler 300 applications listed, so confirm your platform or contact our 24/7 support and we will match it. Every order ships free from our US warehouses, carries a 1-year warranty, and is backed by a 45-day return policy if the fitment is not right.
