Well i had an ebay 3inch downpipe that eliminated the cat before, and i wasnt happy with it. It was very loud and sounded like complete shit. So i sold it for the same price i bought it for(almost), and bought the buschur downpipe/highflow cat to replace it.

That was a while ago, but i finally got up off my ass to intall it. I LOVE IT!! It sounds deeper, and just a tad louder than stock..but overall has a very badass dont fuck with me sound...but it isnt ear peircing loud which is perfect since it's my daily driver. If you're interested in getting a highflow cat, this one is great imo, and the price is awesome.
