Thinking of removing baffles. Pros, cons, and advice needed,

No backpressure equals more decel pop (backfiring) and no reversion pressure wave which DECREASES torque. My dyno operator explained the high torque number I acheived was because of the Kerker touring baffles. I got 98 ft/lbswith a 203 and flat top 95 build,10 ft/lbs more than my 96 with 48s Kerkers with the open standard baffle on the same dyno. I dont't care how young/ aggressive rider you are, most riding is under 3-4k rpm and that is where you feel the loss of torque. My old bike would outpull faster bikes when I rolled on the gas at 60 (high gear roll on) up to about 90 with ease. The open exhaust concept only helps with wide open throttle and then at higher RPM. Decide if you want to actually go fast of if you want to sound faster. I f you want to actually go faster cams and then a big bore are the bang for the buck. Dr Dyno used to insert a steel bar into the stock mufflers, at least on touring bikes and would open/ drill a 1/2 inch hole and they would pick up a few HP at the very top of the RPM band. However the exhaust had a raspy tone rather than the deeper rumble people want. I am in the process of repacking my baffles with stainlees steel steel wool wrapped in fiberglass cloth hoping to tone down my muffs somewhat and increase torque at least a little. If it were me I would check out the slip on muffs from Kerker Supertapp, and best of all they are great folks and made in Ohio.
