Exhaust Header

Match your engine code, displacement, and model year listed in the product title. For example, "Exhaust Header for 2009-2018 Hemi 5.7L" fits all Dodge Ram 1500 5.7L HEMI V8 models in that range. For LS swaps, confirm your donor engine series (LS1, LS2, LS3, LS6) before ordering.

Shorty headers are easier to install and ideal for stock-to-mild builds up to 30% more horsepower. Long tube headers maximize exhaust scavenging for peak power on highly modified engines above 500 HP. For daily-driven trucks and street use, shorty headers deliver the best balance of performance and simplicity.

Yes. SPELAB LS swap conversion headers fit 1923-1967 Chevrolet chassis accepting LS1, LS2, LS3, LS6, and similar GM V8 series. These universal-fit headers solve routing challenges in classic GM chassis. Expect 2–3 hours of installation time with minor fitment adjustments for your specific project.

Possibly on 2006+ vehicles with OBD-II. Header installation changes upstream O2 sensor readings, which can flag a CEL if there's an exhaust leak at the header-to-pipe junction. A properly sealed header usually avoids this. If a light does appear, it typically indicates a loose connection rather than the header itself.

Stock-to-mild builds see 5–15 HP at peak with better mid-range torque. Heavily modified engines with supporting mods can gain 15–30 HP. Headers reduce exhaust backpressure, letting the engine breathe more freely—especially beneficial during high-RPM acceleration and when paired with other bolt-on performance parts.
