If you plan on getting one make double sure the oil lines are not touching the header. Its a tight fit and I check mine before every rode. 1/8 inch is not much clearance. One bump of the muffler and something will be touching somewhere. The exhaust is quiet compared to most but it does its job when gettin on it. If you get the whole system it is plug and play no mapping/tuning needed ,,,,,, at least not for mine. Cost around 1300 if I am remembering right......
