It's started making a rasping sound suggesting there's a small hole somewhere.

Any1 know if you if and how you can get hold of an original replacement exhaust and how much they cost? Are they unique to Williams or the same as the valvers.

I was wondering whether anyone makes a near identical exhaust system but from stainless steel, but I guess this would make my car 'non-standard' due to the extra weight of the SS?

I need to get this exhaust sorted quickly as I'm planning a long drive in a weeks time.
