Well got a Remus backbox fitted (single oval) at the weekend. Looks and fits just great. The noise is more bassier on the idle and really sounds nice 4000 plus. I got it fitted by a guy in Wickford for £20, he specialises in servicing and tweaking Scoobies, though hearing the customer who was before me drive off in a twin monster exhausted WRX that sounded like a B52 taking off i began to panic that my new exhaust would sound too loud. Needn't have done as once fitted the Alfa sound is still there just that much nicer!
