Alright, so after my first thread I went ahead and ordered the Hahn 3" catback exhaust system. The next thing I want to get is a header. Im leaning towards the JBP header because it seems to add a lot more horsepower than other headers. But now I do not know whether to go with the Hahn downpipe or the JBP downpipe, which would you guys suggest? I care more about performance than sound. Any help would be great!

 

There is a thread that has header testing.

the JBP header actually lost horse power.

It is a poorly built header with tons of restrictions.

get a real, midlength header from clear image auto.

 

TRUTH, i am on my third header and my 4th exhaust combo!

Hahn w/CIA header and CAT/CATLESS ( i have both) downpipes are the best!

 

i am running a ZZP 1.75 midlenth and i love it and i think the car does to from the 1/4mile time dropin so much

 

whoa haha thanks everyone!

 

Look into the Vibrant Header/downpipe/highflow cat kit (comes complete) and will bolt directly up to the Hahn cat back:

the jbody header is a bitch to install, thats my .02

and it didnt pick up any hp on the dyno i saw after it was installed
