I don't remember how I got to this site, but I'm glad I did. I posted a plea not long ago for a source of authoritative technical data. I bought a good book on the subject, but this website boils it all down to its essentials.

Yo, down the road,

I agree,
There is a real good exhaust comparison for different models. Showing torque and HP at various RPMs.
