The intake will tend to increase your highway but decrease your city. The exhaust work I'm not sure. Slammin it prolly will tend to increase your fuel economy due to the decreased drag, but if you rub too much then that'll throw it out the window.Originally posted by "sik_civic"
will i/h/e and slammin it lower my MPG? eg hatch
I don't know if i would say that. Maybe civics have a bigger aftermarket than newer stangs, but the 5.0 has a HUGE aftermarket.
I'm sorry, but to me I/H/E is intake/heads/exhaust, not cold air/headers/"fart cannon" j/k.Originally posted by "sik_civic"
yea thank u Sick_civic those ppl with *clears throut* rustangs j/p dont know bout aem k&n and others
Where else would headers fall in? Aren't they part of the exhaust system?Originally posted by "Team 4R"
then where does your header(s) fall in? exhaust? you also need to keep in mind that our intake manifolds and heads are so efficient that 98% of us will never need to swap them out. though there are plenty of options for those who choose to.
you r right man. i got ya!
