Best header/exhaust combo for a 455?

Custom 409 stainless equal length headers, 2.0" primaries, 3.0" collectors. 409 stainless 2.5" exhaust w/H crossover. Borla long case stainless turbo mufflers, 2.5" tailpipes exit at rear bumper.

11:1 462, TA 294-04F solid flat tappet cam: 260°/276° duration @ 0.050", 0.584"/0.603" lift, 108° lobe center, installed 3° advanced.

Warm idle in gear at high stall sounds much like this cold startup...it'll sit and chug at a stoplight in gear around 900 rpm no prob.

Zero sleeper status at a stoplight. It's a dead giveaway unless the person next to you is deaf.

P.S. AM radio non-functional, no speakers. No point otherwise.
