Hinson's headers to y-pipe then midpipe step down from 3.5" to 3" then RB twin dolphin tip.

My first exhaust was 2.5" from the longtubes, to a Y pipe at 3.0". Then 3.0" through a vibrant mid box (6.5 x 4.75") and to an after market RX7 system which had a 5.5" x 10" backbox with a 3.0" outlet.

I've just finished making a new system from the manifolds back. Its a 2.5" dual system with X-pipe, HJS cats and a re-packable back box. The back box is 2.5" dual outlet and is probably a similar size to the standard back box.
