I am thinking about going with an FMF Powerbomb header, and the Q2 muffler, I was wondering if anyone is running this on there YFZ, I want some good performance, but to stay a little quieter! FMF has "the q muffler, and now they have a Q2, has anyone ran with the Q2 muffler!

 

I run the FMF Q2 slip-on with the stock header on my YFZ, and I have been very happy with it. It makes good power and has just the right exhaust tone, and volume. I have owned several aftermarket exhaust in the last five years, including: both Muzzy and Yoshimura on a KFX 700, both Ron Woods and HMF on a DS 650, and both the FMF Titanium 4 and Q2 on a YFZ. Of all those I would rate the Ron Woods best in performance, although it was very loud. I have thought the FMF Q2 has performed at least as good as any of the rest, and it sounds alot better than any of them. Build quality is at least as good with the Q2 as with any other exhaust I have owned, and better than most.

 

thanks for the info
