I have owned several FMF Q-series mufflers. Currently have a Q2 for my KLR 650, and my son's KLX 250. The quality has been good, and the benefits are real. So, I didn't hesitate to purchase the new Q4 for my WRR. Yes, its louder than the original stock pipe, but not a lot according to my sound meter, or the friends who always seem to be riding BEHIND me. It has a deeper tone, and I think it sounds good. Its certainly enhances performance through more open free-flow (breathing) and is several pounds lighter. Slimmer profile too...doesn't stick out so wide and rub on my Dirtbagz like the stock pipe.
But, there's always a "but". Apparently, the packing needs to be replaced with some kind of frequency. The FMF Instructions said to replace the packing at 20 hour intervals. Hhhmmmm....I hear cash register bells ringing. Think I might have exceeded that interval a little. Ok, maybe a lot. One year and 6,000 miles, but whose counting? Everything still appeared to be working fine. But, I decided to refresh the packing anyway....just because I was in the mood to post another interesting article.
Simply logged onto FMF website and found "Pillow Performance Packing" for the Q-series. Sounded close enough to me, so I ordered two sets...cause I'm like that. Sometimes I get a "feeling". And I've learned to heed those HF feelings. Anyway, just like magic it showed up at Rancho Highfive in mere days:

Oh yeah...its SO on! You got to admit, that slogan on the box sure looks promising...
Installing the header & can was very simple & easy. You know...this bike is about the easiest bike I've ever worked on. Anybody else notice that?
