Back on track boys, Lol!!! Worse than a Damn bunch of women yackin! Anyway, I have a Trapp, it's pretty loud, sounds cool but loud. I've heard the HMF & am considering the competition b/c the baffles change out. Looks like a very nice pipe but it's a lil pricey. I wanna run a powerbomb with it so that's an additional cost. Other than that I wouldn't mind the GYTR like Weston recommended but it's pricey too.
