Mine is on and it is very quiet. The muffler is straight through but very quiet. When I called the price for the first 3 pipes was $425.00. I just bought everything for 494.00. So for 70 bucks I got a 40 inch long muffler and 2 tailpipe peices. I used my tailpipe I had as it is 4 inches and stailess steel. The end of it is polished and lookes better than the one from stans. So I got some spare stuff if I need some pipes. Will post more pics after the rain stops and maybee a video link.
