SE exhausts suck, man. there is no big deal going on, just a lot of new-ass dumb-ass bikers thinking the words Screamin´ Eagle mean fast. Any good 2 into 1 collector is great. If you like the classic HD sound, get any of the drag pipes (use straight pipes, add baffles to reduce noise). If you pay more than 100$ for harley exhausts (remember, there is only 2 cylinders) then you are a dumb-ass.
