400ex Dg xcelerator stage 1

Anyone know anyone that has got one?, any pipe for the 400ex only shows moderate gains so I thougt i'd get the cheapest slip on and I think it looks good.

I have one on my 400ex with a power core 4 fmf pipe and you can really tell a difference from stock. I plan on re-jetting the carb soon and putting on a K&N air filter.
