HMF Racing Sport Series Silencer
Robert in MD
Best Sound I have heard
I have just put this on my Honda 400EX about 3 days ago and I will have to say...This is the best sounding exhaust i have heard on a 400ex. Also the power that is added is AWSOME! I will honestly say if you own a 400ex BUY THIS!

Darrin in CA
FMF
FMF Q4 with FMF jet kit really woke up my quad and saw noticable gains in power. I was expecting it to be alott louder like some competitors but it was not. If you are looking for a nice quiet pipe that give you power this is for you.
