yo guys..just installed the test pipe today..sounds awesome!!

the only problem is that i hear a buzzing noise in between 3-4k

its the buzzing noise that i hear from most civics and integras with stock exhausts...like a high pitched bee...ive done some research and havent really found the answer as to why..maybe you guys might be able to help??

installed a 63mm test pipe with my stock piping..

kind of sounds like the buzzing in this video..but not as bad[media]http://www.youtube.com/watch?v=JsQKE52ialY [/media]

 

I don't know if this will help you, but a buzzing noise happened to me and my o2 sensor was loose so i just tighten it.

 

Thats called rasp, and it is to be expected when you remove the cat. Go with a high flow cat, no noise and same power gains. Plus it wont stick, lol

 

My Berk TP doesn't sound raspy at all. It didn't with the stock exhaust and it doesn't with my Tanabe.

 

mine doesn't sound raspy either. exhaust leak, maybe?

 

thanks armend...ill check if my o2 sensor is loose..

hmm..exhaust leak?maybeee...ill have to check..

im actually not running a gasket on..could that be the reason??
