Yoshimura RS4 Reviews

I've read nice and loud in previous post, it's not a loud exhaust, it's perfect sounding. Obviously louder than stock but not over bearing. I've been a Yosh fan for years and ran them on my Dirt bikes, I've also had Pro Circuit, FMF, Bills, Akrapovic etc. and this was my choice for this type of ride/bike. Reasons, performance, looks and the Name. Great product, great sound. 

I have the RS4 slip on and love the tone it is not too loud and adds a little extra power. Very very happy with this purchase! 

Nice and loud

good quality product
