Today I fitted a Flowmaster Super 44 to my Crossfire, OMG the sound is INCREDIBLE. Got it fitted by STS Bromley, and it was a pain but they made it work and I am over the moon. It's hard getting work done on our cars but for the guys on London if you need your exaust upgraded then give them a visit. It's all stainless steel but painted for extra protection. I have included pics.
