This is in prep for its new hybrid k03/4 turbo.. which is >300bhp spec turbo packaged into a k03 fitment, bolt on. Hybrid is fitted, but its old exhaust was never going to be adequate for its new flow potential.. Same turbo internals on a local S3, makes 338bhp/307lbft from 20-22psi boost. okies.. 3 into Lupo does indeed GO 3" TIP - check 3" Downpipe - check 3" Full Bore exhaust - check Comparison to its previous so called 2.5" system (which was 2" internally) The completed 3" exhaust - 3 box system Fitted underside view Fitted front underside view And how it looks from the normal view of the car.. What 3" exhaust??
