  • Was a good performance boost.
Color: black
Bike runs better with this exhaust but it is loud. I had to put a muffler on it so I wouldn't disturb my neighbors. Best deal I could find on Amazon.

  • Expansion chamber

This is a good pipe . Sounds bad a_ _ . Also increased my speed a lot more than I expected. And as you can see, it looks amazing

  • It's very loud
Color: black
It just what the doctor ordered. My bike was bogging and a friend told me to get a expansion chamber pipe and it works great. The only thing is it's very loud just like a dirt bike but my bike runs great. I tried everything and nothing worked. This did.it but you have to get a muffler if you want to ride on the street. I just cut the one off the original motor and made it work. ... show more

  • I was hoping for a upgrade!
Color: silver
I was using stock muffler with cap off the bottom and it flew thought if I got one of these and thought it would increase the power and speed but I was wrong! But live and learn and I learned I wasted 50 bucks

  • Expansion chamber
Color: silver
Fit perfectly with a little bit of man handling(i have a bigger frame)when my old zdx65 would not fit at all, already feel a boost in top end speed and performance, from the half moon pipe i had originally had. Will buy this pipe again for many more builds. Sounds pretty damn good in my opinion as well!! Spring on the tensioner is just plain garbage, just gonna go get a nice one from Lowes or something. I mean it's what I had to do for my previous tensioner as well, is what it is. ... show more
