Pro Circuit - T4 Exhaust System

I purchased this exhaust system for my sons CRF100F Honda. This exhaust does make a big difference when compared to stock. More power output, nice loud tone like a dirtbike should be. Installation was easy along with a nice fit. Gives the entire bike a whole new look. You won't be disappointed.

Great exaust system

I think it was a great deal for my KLX110. It was an awesome present for my birthday, it gave more power and better sound and with a little grease it slipped together nicely.

Great Fit-A bit loud

We put this on a DRZ125 and it really woke the bike up; however, it is way louder versus the stock pipe which may cause some issues with our neighbors when the kids are riding on their pitbike track. The fit and finish was great and it installed perfectly.

pro circuit t-4

I got this for Christmas and put it on a 2003 drz125. It fit nicely. It sounded a lot better and added some low end. Put this pipe, a K&N air filter and re-jet the carb and you have a good combination for low end power. I would recommend this to a friend because it is on the cheaper side of full exhaust systems and gave me more power.
