Just had a complete stainless exhaust (single box) fitted to my '90 CD Carlsson for £300. Noise level is still low, garage wanted to fit two boxes otherwise they said it would be loud but it isnt. I'm really happy with it and would recomend the place to anyone (its in Blackpool).
Also tried a Dawes MBC valve in-line with the APC BCV - Wow what a difference, car really flies!
