Klx250 q4

Excellent addition to bike. Sounds great, works great. Turns the bike into a proper moto. A little issue with fit due to some bent frame tabs. Didn't notice when installed originally, but once addressed all was good.

Lots of Extra

Comes with twice the packing I needed and lots of extra rivets. Instructions (for those that don't already know how to do it) are clear and very simple. This was my first repack and it went very easily. Also comes with the drill bit you need to drill out the old rivets. Great product, highly recommend it!

It fits, but...

Got this thing with the hope that it would quiet down the Titanium 4 that was on my WR450 when I bought it. I might have dropped a decible or 2, but the pipe was still too darned loud. Later, I bought FMF's FS-Approved Spark Arrestor/Endcap for the T4. The combination of the two did not appreciably reduce the noise level, either.

Easy install and sound

Takes about an hour to install. Great sound, only negative is its a little louder in 5th and 6th gear than I hoped. Great price on a carbon fiber exhaust, compared to some of your overrated aftermarket companies. $439 Compared to $600-700. Thats a no brainer.
