Ok-- poor quality control

It reduced the edginess of the Powercore 4 on the DRZ400S, and was happy with that.. BUT, you won't be able to just bolt it on either. The cutout for the screw to attach the insert inside the muffler is long enough. Had to use a dremmel tool to lengthen the cut-out about a MM to get the screw in. Was very disappointed in the quality control of that. Isn't a huge problem to have that fixed on the Jig or press used at time of manufacture. I also sent FMF and Email prior to ordering the insert and got not response. I liked FMF products in the past, but think I'll move on.

Sent wrong pipe

Ordered the pipe for a 2008 ktm 300 xcw as a Christmas present and it's not right pipe. Customer service is a little slow or maybe just busy idk.

Awesome

glad that my header no longer leaks! Happy that the springs came with it. Plus most parts for bikes are expensive but heck this is pretty darn cheap! If you are getting this I recommend getting the FMF spring puller tool! It works really nice

Great for FMF turbine core II

The FMF brand silencer packing works great for my FMF turbine core II silencer, I generally get two repacks out of one package.

Ok exhaust

Bought this for my sons stock 2006 CRF 80 for Christmas as it was listed as exact fit. It did not fit exactly as one of the mounting holes is several inches off and exhaust guard holes do not line up. Had to drill hole in guard to Mount it on pipe. Not what I would call exact fit. Exhaust sounds ok but not much different than stock. Haven't noticed any difference in performance.

Fits fmf powercore 4 perfectly

This is the best wash plug you can get for the money. It fits perfectly in my fmf powercore 4. The streamer on the ends a little cheap though. But other than that, it's great! Looks cool too.
