[2001-400ex'er]

Does anyone know if the Big Gun quiet series is any good because i couldnt find any posts on it and i would like to know, any good power gains, thanks alot

good power gains? NO!

i am not a big fan of this pipe. my buddy had one and it was no better that a stock gutted pipe. the low end power was nice but for the type of riding we do it was no good. if your interested in midrange or top end power, don't get it. everyone has their own opinion on exhausts though. good luck

I will disagree I am running the Big Gun and it is great. The power is felt from down low but it does fall off on top. The great thing is with 3 screws you can open it up if your in a good riding area. Now I am only running a slip on not the full system. Dig Gunis also a great company to do business with and that is rare these days.
