So I have an 03 Acura TL Type S all stock, but I have a Comptech exhaust system installed on it..I was wondering how much horsepower gain I got from that exhaust? I haven't dyno-ed it, I just wanna get an idea.

 

Maybe about 10hp. The biggest bolt on gains are with exhaust headers.

 

no gaining.. only freeing..

 

Yes, freeing.

Its actually about 5hp with axle backs. With a cat back you're looking at 10-15hp.

 

no way 10-15whp. 5-8max. ATLP's are right at 10 and they are the best exhausts for our cars. Still 5-8hp is nice, but you'll only see gains like that if you have headers and CAI to begin with. HF Cat helps a lot too.

 

none, so sell it to me =)

haha

 

Ohh, thanks a lot guys. This helped, and nah I don't got a CAI yet..
