Doug do the headers make any noticeble difference in the sound of the exhaust? I'm looking for that distinct spit or hiss that usually occurs with tubular headers. Kudos on the R&D.

cbsuper, Stillen claims 13hp and 14 lb ft on the catback, have u dyno tested? Also, how does it sound? Someone told me there was a sound clip on a website somewhere but i cant find it. i found it extremely hard to squeeze 10hp out of a cold-air intake, header, and cat-back with my Civic Si but hey, thats a hard engine to get more power from.

 

There is a video they did that shows the sound. It is posted around here somewhere.

 

Yes I think there is a diffrence in the exhaust note it is not loud but they do change the sound. As for the Stillen exhaust we have not dynoed yet with the headers I think the sys would most likely
add power.

 

Nice to see someone from Nashville, TN.

The sound is really nice, specially when he stab the throttle!

What is the final price for the headers?

Going to try and dyno the high flow cats this weekend , hopefully they will make more HP with the headers. Seems like the car got faster after we put them on.
