I am assuming you want to use block huggers for the appearance. I would get them ceramic coated, not sure what manufacturer makes the best. I have Hedman long tubes on the 454 and have had good luck with them.

I'm not worried about engine performance, and I've actually seen data to show that 2 vs 2.5 vs 3 makes very little if any difference. I want 3 because I'll be exiting through the bed and it looks good. Ram horns in the correct angle are tough to find where I am and I got these for free.
