My m4 slip-on is coming up on 5k now which is when it is recommended to repack. Anyone know if I can just leave it? Still sounds awesome. If it gets louder I don't really care lol. I just don't want it to like explode because of the carbon fiber or something. My old bike had two bros and I went 35k before I sold it and never repacked. Just wondering.

I would only repack it if it gets noticeably louder.

If it doesn't bother you why give them your money?
