Side pipes?

Kindof like the Vette's?
I mean I was practically sitting on the exit. At least it had a pretty good bass note,
unlike the screaming banshees on my car; Dynomax 3in x 3out. Actually they only scream between 5 a 7 thousand WOT rpm. The rest of the time they are very nice, with full 3" tailpipes. It's just that from collectors to bumper, the pair are about 75pounds! I told my wife she can't ride along anymore she slows me down too much. KIDDING! I'd never say that to her face,lol. Besides the was only 105.........42 years ago.......
It's first gear, and she spins all the way thru and then some, so 75 pounds ain't no big thing,lol. Lessee 75pounds/8pounds per hp= 9.3hp. Shoot that's only like;3 pushmowers right? Or a 305 chebby
