This is an awesome muffler it isn't very loud on my bike but this i a great buy It has an awesme sound. I have had no problem from it either. It's fitment was perfect right out of the box. iI just put it on and soud awesome the second I started my bike up. The muffler has gave my bike a very nice power increase. Just an awesome all around buy and muffler. I also have had the muffler tuned to give me more power. I also got a mega bomb header pipe which was a great buy too. I would recommend very highly to get both of those.
