Yea, not removed any of the cats [emoji4] oh I did de-snorkel too
both my tuner and mechanic said the uppipe cat would only start to be a problem around 100k (I think they said).
Duncan (RaceDynamix) was quite pleased. He did say he seems to get a little more power from later blobs.
I think Duncan said he thought perhaps three hours of labour to remove the uppipe, so guess it would make sense to do other stuff at the same time. At the time I was quite keen to keep the car as standard as possible and easy to MOT.
I'm really pleased with the results and I have shocked a M5 owner and a Jag XJR (?). A real pleasure to drive. My favourite is the acceleration from 2nd gear all the way through to fifth, just so incredibly smooth and fast [emoji3] id highly recommend it
