Hey guys, next summer im getting a new pipe for my 400ex. Just wondering which one is better, HMF or FMF? Both are pretty good but which provides more power? better sound?

FMF is the original innovator. HMF is pretty damn loud, they both put out comparable gains.

Cobra I don't even think is in business any more... What ever you do, don't get a DG.

If you are looking at HMF, look into their 2010 Series. Suppose to be the best they have in the sport series.

After hearing both and seeing both, I think I'm going with the HMF Utility series. But I have a 500 Foreman! They say you get 15-20% horsepower gain?
