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.

Installed on a 14 3500, seamless install maybe takes 10min. Definitely opens intake up. Noticeably more sound. Not sure any performance gains other than throttle response
I’ve purchased the EGR and CCV deletes as well as the upgraded intake manifold, upper radiator hose and thermostat block, and compressed air piping. Overall I am very satisfied with the quality and fit of all of the parts. Some of the instructions could use a little more detail, but if you are in any way mechanically inclined, you’ll be able to do these yourself no problem. I did have to make a very small modification to the aluminum quick connector on the upper radiator hose in order to get it to lock in place, but other than that everything has been great!
Works amazing and easy to install
too good to not change them!
Slowly piecing this thing back together for the freedom meet this weekend 🤟
Needs more blue 💙
I put these on a ugly farm truck with a cammed LS swap and to keep the ugly “sleeper” feel we had these installed and they worked great for us 👍🏽👍🏽👍🏽
Fast delivery and nice finish on parts
I really do think this is the best DPF back I've ever had. I said it in the video, but the fitment here is MUCH better than MBRP or AFE. I have had both and this one installed so much easier, and much higher quality metal
Made wrong didn't fit
Hi yooo sharing some tips to make everybody's life easier! Slip the rubber boots on before fitting the pipe, leave plenty of rubber past each clamp. It's an easy installation.
Great product/quality
The product was delivered sooner than expected and the product is very well made and added a nice touch to my truck.
Surprisingly fast shipping and decent quality with half of big brands price... will come back!
I was already planning to replace the radiator and coolant tube, so getting the reservoir included made this a great value. Parts arrived well packaged and everything looked good out of the box.
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.
