I am looking for a silencer and reeds for my 98 XCR 440. I don't want twin pipes because that is alot of $$$, and I wanted to know how much I should spend on most bang for the buck reeds. Which kind of silencer do you prefer, and reeds? Will it decrease the life on my engine if I put a silencer, or reeds on? How do I know how to jet it correctly. I want to spend around 200 for a silencer and around maybe a nother 200 for the reeds. Any help is appricated!!!
