As good as they come!

Comments On Oct 31, 2012:Quality fit and finish compared to any other stainless exhaust fitted on my 2012 YZ450F. The only complaint is that the provided spark arrestor is not stamped USFS approved. My left over FMF may fit.

Buy IT !

Comments On Jul 26, 2012:I have a 2012 CRF 450 R . The fit and finish of this pipe is as good or better than any other pipe I have seen. The Dyno chart that Motoworks sent me put base line HP at 47.72 @ aprox 8.2K rpm Torque at 31.50 with pipe 50.97 @ aprox. 9.5K rpm. Here is the deal , you could spend 500.00 more dollars to get aprox the same HP and Torque . If you want to be a name dropper go with the big names in MX pipes. Motoworks has a great rep in the AVT world. Also the the mid pipe and silencer is about .8 Lbs. lighter than stock.
It really woke the bike up. No I don't have any affiliation with Rocky moutian or Motoworks Buy it and laugh at your snob buddys as you roost by with money flying out of your pockets
