I have a 99 warrior and wanted to know what the best exhaust system for it.

 

the fmf megamax2 makes a huge difference all through the powerband and from what i hear so does the white brothers e-series

 

What about a big gun exhaust are they any good???

 

The E-series comes in S bend and megaphone. I
didn't see any diff. in mine until I put on
the pro-flow air box adapter. I had a stock
style K&N with holes in the lid but it still
didn't let in near the air that the no lid
set up did. No matter which pipe you get you
have to let it breathe. More in, more out.
I think the E-series is a good pipe plus it's
trick looking.

 

had a 99 warrior, did some mods. Had a White Bros E Series and ran 7 discs. Not too loud, worked great. Highly recommend it.
Just bought a 2000 400ex.
