cold air intake and custom tune.

[Fletch]

hi just wondering about a round about price for a blue power cold air box and a custom tune on my ba manual xr8 ute. when i bout it came with a herrod exhaust consisting of 4 into 1 mild steel extractors, 2 1/2 inch cats, (gutted), twin 2 1/2 inch stainless pipe into a muffler just before the diff, into a single 3 inch stainless pipe over the diff and another muffler, then exiting in twin 2 1/2 inch pipes. and just wondering with the tune, cold air intake and exhaust what sort of power i would be looking at and is there anything else you suggest.

cheers fletch.
