Outer Limits 4x4 Board

Hey guys the time has come to upgrade my zorst in the 80 series so wats your opinion on wat i should get done and any good places on the north side of brissy. I was thinkin extractors with 3inch pipes.

What engine has it got? My 4.5 litre petrol has extrators and 2 1/5" pipe with a hooker areo chamber muffler and its fine maybe a little loud..

Beaudesert Exhaust does a great job [they were a bit exy when I had some custom work done]… http://www.beauexhausts.com.au/quote.htm
