Is anyone familiar with or has Curtis Sparks exhaust system? I have a fairly new 400EX in need of MORE MORE MORE power. The curtis sparks system was reccomended. Anyone else have that system on their 400EX? What kind of improvement did you get?

It's one of the top 5 best exhaust you can get for you quad. A search for exhausts will turn up plenty of info.

I had the Sparks and wasn't pleased with it.
