Header Poll thread
Header Poll thread
Im looking to get some info on how much headers effect mileage. If you have a header installed can you post your before & after mileage & addiction mods you had. Thanks!

My mileage never really changed from any of my mods. I think a header is the best mod you can do on this vehicle. The stock manifold is horrendous.

I agree. I put on a CAI and Magnaflow exhaust first, but the header made the most noticeable difference.

I know it has to do with the car breaking in more too, but I saw a mileage increase as I modded. The header was definitely a nice mod...
