400 EX Owners Please Help Fast With Problem!
I need to quickly know which exhaust is better for the 400 EX: either the White Bros. E-Series full system or the White Bros. R-4 full system. I ride wide open alot and climb hils, etc. Which is better overall? Thank You. Your thoughts are very much appreciated.

hmm...i voted against using the E-series full system but i never approved the R-4 full system.
hmm....just take the spark arrestor on the back end off....it gives it so much more power...just make sure things dont overheat, i only tried it for like 10 minutes
