Exhaust Header
SPELAB Exhaust Headers
header exhaust, also known as exhaust manifolds, are designed to channel the exhaust gases from the engine's cylinders to the exhaust system. Here are some potential benefits of installing an aftermarket exhaust header:
|
1.Increased Performance |
By improving the flow of exhaust gases, an aftermarket exhaust header can increase engine power and torque, especially at high RPMs. |
| 2.Better Fuel Efficiency | An aftermarket exhaust header can also help to improve fuel efficiency by reducing the amount of work the engine needs to do to push exhaust gases out of the cylinders. |
| 3.Improved Sound | An aftermarket exhaust header can also change the sound of the exhaust system, making it louder and more aggressive. |
| 4.Reduced Heat Buildup | An aftermarket exhaust header can help to reduce heat buildup in the engine compartment, which can help to extend the life of engine components and reduce the risk of engine damage. |
Upgrade your vehicle's performance with the SPELAB Exhaust Header. Our range includes options for various models such as the 5.7 Hemi, IS300, 350z, E46, G35, and more. Whether you're seeking increased power, better fuel efficiency, or a more exhilarating exhaust note, our exhaust headers deliver unparalleled performance and quality.

much cheaper than big brand and seems good quality, thank you Spelab.
Price was great w heavy discounts. Great 5R110 6.0 powerstroke aluminum, Red, deep pan. W bolts and gasket. Great packing and instructions.
This kit came with everything I needed to get the job done. There's a great SPE lab video online for installation help. Every piece felt quality and was simple enough to put together. Had extra hose after running all the way to the back of my rig so there's plenty provided. I just ran mine to atmosphere so there's a popcorn sound at the back of my rig now but it doesn't smell terrible. Definitely recommend this upgrade for anyone who wants a healthy engine. As for how hard the installation is, if you can change the CCV box you can install this kit.
Installed this SPELAB thermal bypass valve alongside a deep pan upgrade and the setup works flawlessly. Trans fluid temps drop fast and stay right where they should be.
The overall fit was great and the build quality feels solid. I noticed a past review complaining about the O-rings being the wrong size—just wanted to clarify that those O-rings aren't for the bypass block itself; they are meant for the metal threaded filter adapter. Don't let that review throw you off. Solid 5 stars!
Surprisingly fast shipping and decent quality with half of big brands price... will come back!
fits well, would be better with instruction.
love this red! Customer support is also very helpful. Hope it will last.
Love it! Fits my 2017 F250.
The fitment was fantastic And it went together really well and fast
Great shipping. Great product. Was easy to install even though I had to cut some pipe off but overall happy with product
Solid intake manifold, no fitment issues.
Fit perfect and was of high quality material I have had the plate on my truck for about 2 weeks now and it is working great thanks SPELAB
The cold air intake was easy and fast to install. it looks great and boosted my truck up a little for performance without breaking the bank. it’s the best bang for your buck even if your truck is stock or built it’s worth the money
hard parts are amazing and everything went together great
Install was easy and straightforward. Everything lined up nice. Peace of mind knowing there are no worries about potential destroying my engine, due to a nut.
Exhaust Header FAQs
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.
