i have B&B tri flow exhaust installed, and it sounds really good very european, however i don't think that it is loud enuf... I am looking into buying an exhaust soon. I have been looking mainly at Remus, but a friend of mine mentioned that Tri Flow was good. I want an exhaust that increases power and is loud. I assume all the exhausts have the same increase in power, so I need some help choosing a loud exhaust. Please make suggestions on exhausts I am unaware of. Thanks.
