I just bought a 2000 xr600 with 25 miles on it and I am about to do some mods. Does any one have any experience with the white bros e-2 series slip on? My choices for exhaust are the fmf power core 4, white bros e-2, the supertrap IDS2, big gun, stain tune and possibly the up-tite systems. These will all be slip ons. Which one will give the best performance without being obnoxiously loud. I live in Connecticut and would like to keep the db level below 102 if possible. I will be adding and edelbrock pumper carb, one of these mufflers, and a new airbox/filter to be determined. Any help on the exhaust and air filter would be greatly appreciated. Hopefully someone has the exact bike and can speak from experience. Thanks alot.
