Lose any low end torque? An engine needs some back pressure, on the exhaust valves for the powerband to stay relatively flat through the RPM range..

thought about those. i decided i didn't like how they don't hide the bottom frame rails. they sound pretty great, though.

Not that I can tell. There is a nice removable,wrapped up baffle inside. So it's not like straight pipes. I think there's enough back pressure there.

This one is when I put them on my speedmaster

The worked fine...didn't notice any change over the BC cocktail shakers....I just got tired of the noise, right under me so I put the BC cocktail shakers back on

Sound great - how do they compare to say Tors? I could only get the rear baffle out of my stock pipes and looking at some other options. Don't want obscenely loud but something better than what I have

I can't say....haven't had TOR in a long time...like I said I got tired of the noise right under me...Seems to me the BC cocktail shakers and cannons are about the same noise...it is just where it is under you or back a little bit...
