I just traded my kfx400 in for a 450r and.....WOW, that thing is unbelieveable. I am in love with it. I was just wondering what everyone's opinion was on which company offers the best slip on for the R. Thanks in advance!

 

HMF [img]i/expressions/face-icon-small-smile.gif[/img] great gains and well built.

 

Sparks Or ESR

 

I like my Yoshimura made a big difference

 

I bought the Bill Balance HMF full exhaust. It has nice gains all around and delivers smooth performance. I originally was going to get the Curtis Sparks but the 104db changed my mind. We all need to do what is best for our sport, and being quieter is good. Besides the HMF exhaust had better dynos and are still quieter. I called White Bros about the E2 to see if they had a head pipe available for it. He said they would have one available next week but I decided to go with HMF anyways, nice company to do business with and they seem to be very honest.

 

Sparks - ESR - LRD

 

LV,

You need to stay consistent. In a previous question on which is the best exhaust you said you'd take the HMF over an LRD. Now you're telling this guy to get the LRD, whats up with that?

Do you have the Yosh full system? What jetting did you end up with? A friend of mine just purchased this exhaust for his new 450R.

 

I did a lot of checking around and I went with the HMF BB pro series slip-on.It makes awesome power,sounds great and with the TRM (torque range modifier)installed really brings the bottom end power on.When I put the hrc kit in I lost some bottom end but the slip-on brought it all back and then some.I am sure that some of the others recommended would be great too.Also the fit/finish is excellent.
