    Here's my full 3" exhaust setup... completely bolt on, only parts that I welded are the hangers.
    Had the turn down tail pipes exiting in the middle.

    I have 2.5" magnaflows with turndowns and 2.5" with X pipe (pypes) from the headers on a 520hp 406.
    It's not actually too bad. I have 12" extensions past the mufflers to just under the rear end.
    But I'm not sure that system would support 600hp - in theory 550 or so.

    Full 2.5 Pypes with x-pipe on a 383. 470ish hp at the flywheel. I would definitely go 3" next time, and I may do it this summer. 2.5 is nice, but 3 is proven to make more power. And its louder. Avoid the hollow sound by dumping under the car.

    I have 3" all the way back, x pipe and I don't know about any hollow sound.

    It is more raspy to me with the smaller pipe, I like tighter sound to it the 3” made mine sound drawn out
