i just bought a hmf is it a good pipe or is a big gun or an e-series better or maybe an fmf and will jets and an air filter make a differencewith a pipe!!!!!!!!!!![img]i/expressions/face-icon-small-confused.gif[/img]

 

I have heard that hmf is the best one. Good pick>

 

hey kracker what about the jets and k&n will they help the pipe make the motor stonger

 

Curtis Sparks x6. You will love the performance gains from it and it is in my opinion the best pipe out. Later Slim

 

what is the website for the Curtis Sparks pipes??

 

www.sparksracing.com

 

outta the 3 of them white bros e-series is the better 1 it provides hp gains throughout the whole powerbrand and revs out pretty good and it better it u re jet and get a air fliter ur 400 will run at peak proformence 400exs for life!

 

I just sold my 400ex but i got the new LRD Pipe for it and loved it. Just a thought.

 

I have a T-4 and my friend has an E-Series, there both very impressive. I've seen 2 ex's with FMF megamax and i wasen't very impressed.

 

who else had the megamax? i know jay did but who else?
