Will fit a 2006 GasGas

It comes with a tag that says "03-06 GasGas 250/300." I put it on my 2006 GasGas EC300 to replace the FMF fatty pipe, and it makes a huge difference in power delivery. It has all kinds of grunt down low, and it pulls hard through the mid range. I did have to drop a pilot jet size. Its a great American made product that looks great, and fits well right out of the box.

Good Pipe

I bought this pipe to replace a Pro Circuit Platinum 2 that I crushed beyond repair. The power delivery with this pipe is very similar to my PC pipe, but with maybe a bit more low-end. I can't perceive any difference in mid or top-end performance between the two. The FMF seems to be of a slightly heavier construction too. The only complaint I have is that fit could have been a little better, as it took a good deal of work to get it installed. But I was able to get it on and ready to ride without too much effort.
