I have the Sparks exhaust and I am very happy with it. The power increase is very noticeable, the throttle response is awesome, and the top end over rev is excellent. All the steel is chromed including the end cap which has a turn down on it. The canister is aluminum and I think the system looks really good as good as any other exhaust I have seen.

I personally feel the exhaust is better than the Big Gunn from what I have seen. I ride with a guy who has a 440EX and my machine will run with him even when we get out in the open. I know he has more grunt than me, but I think I make up some on the top end.

I also bought the jet kit, and foam air filter Sparks sells. It all cost about $390 and I think it is fair. The craftmanship is excellent the welds are immaculate, the chroming is top notch, and the engraving is also very nice.

The exhaust is very loud, but honestly so is the BIg Gun. I think if you can handle the noise of the Big GUn you really wont notice the SParks any more.
