I'm just curious wut would be a good exhaust for my DVX. I have been looking at Twobros, Pro Curcuit Type 496, or possibly White Bros E2 exhaust. I'm not going for all out racing or anything, but i'd like a boost in all ranges from low to the top. I ride trails and along a river, along with riding dunes. So which o' these 3 would be better or is there a better choice for me out there that hasn't caught my eye. Any help would be greatly appreciated.
