OK, decided car is a bit on the loud side (well the police and neighbours have) so need to sort it out. I’m going to keep it d-catted so require an original 965 muffler. I would be happy to do a straight swap for my muffler by-pass or cash.
It does sound a bit agricultural at idle however, on the go it's bloody great. The other issue is there's no quite mode, which led to the run-in with Mr Plod (who was actually a nice chap).
