I picked up a real RB 12A collected header for the FB. I come from big honking V8's or big honking turbo cars, so all of my stuff has had huge exhaust on it. Why not a single 3" on a 12A? Does the 2.5" flow sufficiently?
Here's what I'm thinking parts wise, though still undecided on size:
RB Header > Magnaflow Welded Ultraflo Bullet Muffler (it will look like a cat and act like a resonator) > custom mandrel bent piping over the axle > Magnaflow Sport muffler (either dual outlet, or if maybe a big single, or maybe a single outlet muffler with a dual tip added on before the valance so it looks like the original dual-outlet).
Anyways, need thoughts, facts, and opinions.
