Haven't done it yet but i am determined to put twin stacks on mine, gunnna go with 2" headers into a cat into a splitter into twin 2" pipes with a freeish muffler on each one

mind you ill be running a EJ22, probably stroked to 2.5 and maybe a turbo

Make sure to X pipe the exhaust, you'll lose vaccuum scavenging and thus HP otherwise. Plus it will sound really bad.

Basically you want (off an EJ22) 4>2>1<2.

If you're doing it on the EA81 most of the aero sites recommend a cross pipe between the headers under or near the sump.

There's a guy cruising around bendigo with his brumby done up to the hill for cruising. He has a twin exhaust system setup, looks pretty mean, done the same way ppl do the 253 holden utes... I'll stop and pick his brain next time i see him.
