Well, I did the mufflerectomy and holy **** was it a pain in the ass. After **** near breaking my hand about 4 times i finally got the **** out. Is it worth it? No. I do not like the sound at all and judging from my butt dyno Ive lost a little in the bottom end. For a balance of sound and performance, and for free, just punching out holes around the baffle was better. I rode the bike after just punching holes around the end and it sounded better than after i took out the entire baffle. Well, this was my experience and I hope it helps someone. Oh yeah, BUY THE GALVANIZED PIPE! I did not and it was HELL.
