Ive just realised that the ‘bypass’ I mentioned is actually a plug and play module which I’m assuming is to avoid engine management lights coming on when the GPF is removed.
Mate, when you say ‘GPF delete’ would that be what the GPF bypass is referred to that Milltek are doing or is that something completely different?
Just want my S3 to sound better than it does now and I’m not sure how to go about it as cheaply as possible!
Any of you guys had Milltek’s GPF bypass exhaust system? About £290, just wondered if this is a viable option to get the sound back without failing the MOT?
