thanks everybody. i talked to a big giant brain at the local hot rod muffler shop over the weekend who told me that I can't beat tri Y headers. they are supposed to be even better than 4 equal tube headers for torque because the cylindar that's off will help scavange the others. He recommended i stay away from flow-tech's brand due to poor quality control, and only get the doug Thorleys, which is the same thing i've heard for what to get for my 326 pontiac. Until I get $350 for the Thorleys, I will stick with the 2" Rams Horns, because the shop said it would only be $60 to change over my coming new exhaust once i buy and install the headers. Besides, I have had my old motor (same mill /different cam) up to 6300 with my rams horns and my new cam stops at 5000. I need to get a new exhaust on both car and truck and was recommended to go 2 and a half inches to the muffler (flowmaster) and then 3 inches out the back of the car. cost $450-$500!! OUUUUCHHH! Can i have a reach around with that???
thanks again for everybodies input.
