t4 slipon

Hey,

Ive just purchased the pro circuit "t4s" slipon for my bike. Its the same as the normal t4 slipon but the t4s has the newer stickers and comes with free spare muffler packing etc.

Anyway i ride closed course so ive removed the quiet insert with the spark arrestor and installed the other insert that comes with it. My question is whats all this talk about the tunable end cap ? Hows this work.

BTW my brother has a t4 slipon and his insert is quite larger then mine, Im going to swap the 2 and see what i like better, but can i buy a bigger insert ?

Thanks for your help....

I think that you can my little sister has a KLX110 with a t4 and the insert is like 2 inches diameter!! I think that is overkill for such a small bike but it sounds awesome:lol:
