Darn it Jam!

Now you are going to confuse him! YES, what you say has volumes of technical reality to it. Could you be talking about....
"back pressure?" Yup, well sort of anyway. Heat is important, smooooth excavating is also good, BUT dumping 151 cubic inches, which equeals volumes of exhaust into a 1 1/2 +/- inch tube that dumps into a wall, forcing it the other way into another 1 1/2 +/- tube, before exiting is a total "Torque" killer.

Better than stock..that's all.

DV

PS...wonder if I can find some spiral inserts that will fit??
