rev box for 300ex

[300ex1615]

been thinking about getting a revbox for my 300ex.. have heard so many things about if it's a wast of money or not. white bros pipe, k&n air filter. will it do me any good?

I personally do not think they are a waste I have a Big Gun Rev Box on my raptor 660. It has A Yoshimura pipe, k&n, Hotcam stage2, and dyno jets.i think it makes it a little faster on the top end and improves throttle response. we have a procom rev box on each of our 400exs and a big gun on our 300ex. same response on all of them. not much $ on ebay.

my brother had one on his 05. and he had a white brothers e-series header and an hmf silencer. he had better throttle response, and more power. when we put our stock filters and pipes on, he pulled away from my 04 in all gears. he even had more lower end power. real snappy bottom end power. i would recomend one dude
