Good fit and sound
Fit the stock parts of the bike great and the new PowerBomb header. Had to do a little bit of grinding on my Pannier racks (Zega).
Sounds great at idle and better when on it, a bit louder than I had hoped for, but certainly not obnoxious. Stickers came off nice and easy (I'm not the sticker type) and the quality USFS sticker got put on. Fantastic finish on the can

Scotty I need more power
The Enterprise (KLR 650) has some more power, notice it more off-roading in all ranges but I also added the FMF Power Bomb Header Pipe. Only loud when you want it to be and I'm very happy with the purchase, would do it again.

Best option?
My original FMF pipe blew apart after 15K dual sport miles, o yeah this was the cheapest option and i went with it again. Watch out the frame bolt is too short and wont thread in. The old pipe had a nice welded on nut, this one had a chintzy steel tabnut, so you might be in for a trip to the hardware store to find an M8-1.25x20 mm bolt. Locktight the spark arestor it'll fall out easy too. Other than that it sounds great and improves power so long as you keep it full of fiberglass!

lighter than stock but too loud
Decent build quality, lighter than stock. Does not use the Yamaha EXUP valve. I used this muffler in conjunction with a DynoJet fuel injection reprogrammer tuned professionally and it gave the bike better throttle response and more low to midrange power, or so I thought.

After much use commuting on surface streets and some race track laps, I found it too loud for street use, despite its Q label. While it can be acceptable droning at low RPM in a high gear, it is especially obnoxious accelerating.

Reverting to the stock exhaust did not change the throttle response or power delivery, which was improved by the EFI reprogramming, not by the loud muffler.

Basically this thing is a noise maker that shaves a few pounds.

What is the difference between the FMF Hex Q4 S/A Silencer and the FMF Q4 S/A Silencer? What does "HEX" mean?

BEST ANSWER: The Q4 Hex is the newest model and supposed to be quieter than the old Q4.
I have the Q4 Hex on my CRF250L and love it. Defently louder than stock by quite a bit.
does the installing of the muffler require rejeting the carb? In order to not hurt your fuel consumption.
A shopper on Jan 30, 2017
BEST ANSWER: For best performance conditions, you may need to rejet your bike. Once the silencer is installed, you can see how the bike runs and then determine whether or not the carburetor needs to be adjusted.
when do you repack muffler?
