Gonna buy an exhaust kit. I would like advice on which size pipe and why. I have a .30 over 455, e heads (out of the box), Comp XE274H cam. Motor will make around of 480ish hp. I believe in the Jim Hand book he used mandral bent 2.5" pipes. He said that 3" is too big. The car is a 68 convert with a 4 spd manual trans. The system will be stainless to rear bumper. I'm looking at a kit from Summit with dual muffs and either a Pypes or Magnaflow mufflers. Thanks for the help. Steveo
