Mines a 1.8 twinspark on a W. The first owner has fitted a Remus DTM back box which is nice on the eyes but you wouldnt know it was there in the car
If mine has a pre-cat and a cat, I might be tempted to remove the centre box to setup the volume and get the gases moving a bit more freely.
Better not tell the missis, noisy exhaust has been a touchy subjet since we meet lol
