Quads on an AU XR8 Ute. Anybody done it?

[b2tf]

Gday all

Im on the hunt for info in regards to a quad system for my ute, going to give it a go and see how it turns out.

At the moment I have a Herrod 2.5" single system on there (Y piece after the cats then goes into 2.5" from there). Im wondering what the best way to go about setting up the new system will be, was thinking either twin 2.5" with each pipe running from each cat then just going straight back (obviously bending round the fuel tank), or whether I should go 3" from the Y piece back (would it fit up ok?), then split into twin 2.5" after the diff?

The second option (split after the diff) is what an exhaust shop here reckons I should do, but they also said twin 3" which I reckon would sound bloody loud and run like crap. I want to keep the performance aspect of it, and Im not *too* fussed on noise - I want it to sound good (I like the sound I have now but wouldnt mind it a little bit louder), but I dont want a bloody big system that is going to lose me power.

I can get Lukey systems thru work, was thinking I could get a 3" Super System catback, then split it after the diff.

Has anybody done this type of setup (quads) before on an AU, if so, what did you use, and how did it sound?

Also, Im assuming new hangers will have to be added for the LHS pipe?
