Hey so I am looking to get a spark arrestor for my bike, probably just a end cap. While I was at it tho I have an 03 YZ450 and it has the stock silencer on it that goes out to the edge of the fender. Would I be able to cut it off a little past the mounting bracket and put the end cap on there and not loose any power? or would I gain power? And also would it be louder or quieter? thanks.
