I have one on my 450R and I like it a lot! It's a nice pipe! The pipe made a big difference over stock. A friend of mine has a slip on for his YFZ. It also made a big difference!

I was searching the web for some info on these exhaust systems and I came across a shootout that was done on a crf450 bike.The CHM came out on top with a second place to Pro Circuit,third place was HMF and then Big Gun.They said it was an awesome pipe on the crf so I was thinking it might be real good on the trx.

Z-135,how loud is this pipe?

One of the guys i know just got this pipe and he loves it, they have a low retail price and they are one of the best pipes available for the 450r. If I already didn't have a sparks i would get one of these.

I checked out their site today and they show both 450's dynoing with the same hp of 35. Kinda strange since everyone says the Yfz comes with more stock. Is one the full system and the other just a slip on. It says the yammie is a slip on but doesnt say on the honda. SOMEONE pls get this and tell us how it works

The guy that owns CHM told me that the reason for only having a slip-on for the yfz is because there is no gain in having a different headpipe on that quad, on the 450r there is a gain in swapping out the headpipe and that's why its offered. If you guys contact him he can give you all the info you can ask of him. This is the man how makes the best pipes for the crf450 and he uses that knowledge in his 450r pipe plus some.
