I am trying to find an audi specialist garage to fit a Top Gear Exhaust to my Audi R8 V8. I live in Richmond, Surrey. Sadly Top Gear in Bridport no longer do this.
Top Gear and Longlife are all part of the same group - Longlife uses higher quality steel and silencer boxes, so I'd be tempted to have a look for a local Longlife franchise (probably Carshalton for you)
