I'm more interested in performance than sound for an exhaust. could anyone tell me which exhausts would give me the biggest horsepower gain?

 

PLEASE

 

i've searched alot. no one actually tells the gains....im ordering soon so im really looking and need help. theres not much even in the sticky.

 

good idea! and just to let you know, there are threads about this. just gotta dig a little deeper.

 

if u know the page, just post it please. im just looking for numbers.

 

In general terms, an axle-back alone won't give you much, if any gains. However, a full exhaust (header, s-pipe, cat-less mid-pipe, and axle-back) will give you somewhat noticeable gains. There are a lot of variables with a full exhaust, so you won't find your answer in one post.

 

thank you. it all depends on your setup.

I've personally got the HKS Hi-Power exhaust and my butt dyno feels an extra 5HP
