Hi all,
Just a quick question, I recently bought a 3" greddy power extreme II cat back exhaust system with a 3" front pipe, the thing looks great and really isn't that loud (if compared to whats around) but has a nice grunty sound when you accelerate(not a droning noise), Now I thought I would be Pro active and go to an exhaust outlet that is a EPA approved noise tester and get a noise test done to my exhaust at EPA standards, just to see how I would fair, to my dismay the exhaust had a sound pressure reading of 93db(a) (90db being the legal limit), just 3db over the limit !!
Question: Is there anything that can be done to easy that sound pressure down a little?? any tricks of the trade?? can the exhaust be wrapped to help deaden the noise ? or is there anything else that might help drop the sound pressure down just a fraction? please help ....
PS Please dont post stupid obvious responses like, put your stock exhaust back on, or you will get a public for your troubles...
Thanks all.
