Not sure if i asked this before but:
1. will car pass NCT with Sports cat downpipe fitted?
2. Does sports cat need to be mapped for straight away or will more gains be had from it when mapped? will car run safely with it fitted?
3. Anyone recommend a place that is good at custom exhaust work? Might need to change flange on new pipe to mate properly with my turbo.
Cheers
