Decided to get new Silencer

The question is what one? Any recommendations? I ride a 02 WR426 and race desert in Hare Scrambles and Hare and Hounds.

fmf q. I have the fmf factory 4.1 with the 96 db insert on my 07 and I blew a 94 at the last enduro that I entered. The Q is probably a better off road pipe straight away, because it comes setup to pass sound in stock form. I have also heard that setting up yz exhaust with a pro-moto billet sparky works pretty well and is cheaper if you can track down a yz can.

Don't limit yourself to the few options listed for that bike. Exhaust opts. for 03-05 should fit as well. I tried a DMC silencer from an 05 on my 01 and it fit with no problem. If you don't want to take a chance then I'd recommend the FMF Q2. I'm thinking about trying a Q4 on mine. Much shorter tahn Q2.

In the past I have used the FMF quiet core, and liked the results.

Rocky Mountain MC is currently marketing a LEXX pipe for four wheelers. I am currently testing a WR450 prototype and love it. It is a good looking pipe with several inexpensive performance options. I currently have a quiet core tip in it. For under 15.00 the pipe can go from a quiet core to several different racing options. The pipes are less expensive than other aftermarkets. I would imagine the price would be similar to the ones RM MC has listed for the four wheelers. I am told they are going to make pipes for the older Wrs as well.

Cool thanks for the responses!


Leo vince... I order one for my 08 WR. UPS is delivering tonight. I got mine for $314 OTD.
