Hey all!
My brother is upgrading to a T3 in the next week or two, and being a true aussie bloke, is already thinking about needing more power... He has been told that the exhaust flanges are smaller than they could be (or something to the effect - for ADRs), and that increasing the size of them will help it all flow MUCH better and pick up some well needed KWs

Is this lagit, or just s*** ?
THanks!!!
