Twin exhaust!!!!

[Storme93]

I want to get a twin exhaust fitted to the old girl (AU2 Sedan)

By twin exhaust I mean like the xr6 turbo B-series has, I'm just wondering if anyone has done it or tried to do it?!?! I'm going to Brisbane in two weeks and was wondering some good exhaust shops to ring up and talk to who may work with me on fabbing it or whatever is required. I also don't have a **** load of money to spend so I don't want them to just charge me ridiculous prices for development and all of that B.S.

Thanks to anyone that can help

I build my own twin 3" exhaust system about 10 years ago. I split the extractors into two sections, twin V8 cats from there twin 3" into a twin entry 3" muffler at center location, with single 4" out, 4" over the diff and exit.

It was designed around a fairly worked high reving I6 engine with pretty wild cam etc, lost a lot of bottom end, but in combination with 3.7 diff gears it revved quickly through the bottom end and stayed in power range from there on in.
