cool. what sizes have you left? my down pipe is HKS. thought it was 3 inch but just looking at a tape measure now and 3 inch looks quite small so I'm not sure what size it is till i get the car back up on the lift. a shame to go cutting a brand new hks down pipe but sure its better than breaking manifolds every time your out. is there a preferred position on the exhaust system for the flexi? or is it once its in there and fairly close to the turbo or what? cause where i would have put it, Robbie (DTP) has welded in a threaded test point for when he's mapping the car,so it will have to go in where the down pipe straightens out after the bend (not turbo side of the bend) if ya get what i mean? would it do the same job there or what do ya reckon?
