hey i was wondering the advantages and disadvantages of shortening a exhaust can. I cut my old akra. but didn’t really notice a hp gain or loss. just louder. Rumor has it that when u cut it u gain torque and lose h.p. or vise versa. any one know for sure? ---

to be honest with you the little gains with adding a slip on can barely be felt. Cutting the can will most likely do nothing but make it louder. ---

I wouldn’t bother cutting one, seems like too much work to just make it obnoxiously loud If you really want the extra rwhp, look other places ---

I just had to prove a point…if u read SPORTRIDER magazine people would see exhaust comparisons with dyno graphs often. ---

best guess is changing the length will change the harmonic of the exhaust pulses and move your peak torque…I would guess up. I think all it will do is make it louder. I wouldn’t expect a [useful] hp or torque increase. ---

3-4 hp is alot for something that weighs only 400 pounds…i notice the difference. just like riding when it is 80 degrees outside then riding when it is 40 degrees outside. every 10 degrees is 1% horsepower. ---

-1, +2 for the street on your new bike, although on a liter bike i could see 3 hp being gainable from an exhaust, however, its not gonna sound as throaty on your new bike… however, i think the shorter muzzy can would look nice… so do it if you want… ---
