Does anyone have this exhaust fitted

[Sean]

I was wondering does anybody have a xp taipain exhaust fitted to a 1997 gq patrol 2.8 turbo deisel if so where did you get it and how much.... Or if anyone knows of any good places in sydney to get a 3 inch mandrel bent performance exhaust system from. Also is there a different exhaust note to steel to stainless steel or are they the same.

any help would be grateful
