I'm looking at getting a full Yoshi RS-3 for my 01 400ex. I hear they are amazing pipes. What do you guys think? I also like the fact that they come with different volume inserts, handy when you don't wanna get busted by the DNR.

 

i have a full yoshi exhaust on my trx450r, it the TRC comp pipe but i love it i think all yoshi pipes are pretty good. it gave me a great hp gain and a lot of bottomend to.

 

i had a full yoshi pipe on my raptor 660 it was nice

 

Well does anyone think there is a better exauhst for the same price, or any pro's or con's with Yoshi pipes?
