How much of an increase in hp does the comptech catback exhaust system give?

 

Comptech and most if not all cat-back only systems only gives you about 2-3 hp gains. Headers gives the largest gains, 15-20 horses

 

0-3 whp

 

shi bal nothing is what it gives you

 

I thought headers were closer to 30 hp??

 

skip the muffles and get the bpipe, thats where most of the gains are in the exhaust systems. i believe its been dynoed at 4-5 whp. mufflers are more for sound/show.

 

i thought it was more like, 2-3 for the bpipe, then 2-3 for the mufflers?

in any case it's not worth the money if you're lookin' for gains unless you're running forced induction.

try the search button, exhausts have been discussed over and over .

 

save your money for some headers
