fmf gnarly
The product arrived expertly packaged on the day DK said it would.
There is a problem with the fit, considering I am replacing a Bashed FMF gnarly with an FMF gnarly one would expect a perfect match, Nope, one of the pipe mounts is an inch off.
I have skills to compensate but many people do not so the bracket would be a show stopper.

A+ for FMF
I got this pipe after a recent rebuild. I was happy with the stock pipe on my '93 CR250 but during my rebuld I found the pipe did not fit properly. The Gnarly pipe fit better than the stock I thought. It is tougher than the stock or other pipes I have seen. I was more than happy with the power delieverly. Gave the bike more usable power in bottom and mid for the power band. Which is what I was looking for woods riding. If you are riding off-road or doing hare scrambles, this pipe is a must!

FMF Gnarley Pipe!!
The pkg was on time as promised, and fit and finish were perfect on my 250. I would not say the gains were super huge; but, is an improvement over the stock pipe on the low and mid ranges which is great for the single tracks and some tighter motocross tracks in the area.
