I have 600 to spend on an exhaust and I'm going custom. I want to get a burns stainless muffler and keep my stock tip along with a high flow cat. Just wondering what length will give me the best sound. The longer the muffler is the deeper the sound right? or is that backwards. And are they good quality, worth the money? i read that they are good products and i want something that is really light in wieght. I take it kartboy hangers won't work on this? I work at a dealership so i have access to a lot of stuff. Just want to get everything figured out before i go and order all this s***. thanks.
