Sorry I wasn't clear on my answer Butch....Because I took out 3 baffles, my bike seems to have come alive and runs quicker now. The rumble sound i've achieved is because the baffles have been removed and it's a freer flowing exhaust. The cross over hose was only put on yesterday because of knowledge gained here and I haven't tested the bike out yet with that mod done. Thursday, my dealer is going to tweak the carbs for me. I'm learning new things about my Speedie daily as I read posts here, ask questions and talk to the Guys/Gals on this great Forum. Having access to this Forum was a big factor in my purchasing a TBS.
