I am at stage 1 with my edition 30 and the constant itch to tinker is growing. Thought are to get the high flow down pipe, cat and induction. However I really don't want any increase in noise if possible. For those who have gone/did go stage 2 was it worth it ?, the downpipe etc is looking like £700 ish and induction at £300 it's 1k for anther 30 or so bhp. Obviously stage 1 is best value per bhp but not sure if stage 2 will make the car worse than stage 1. In terms of drivability ?. Will for example fitting the APR downpipe make it louder ?, will it make any difference to the stage 1 software (whilst I decide which mapper to use for stage 2). Do all downpipes and high flow cats work with the factory cat back exhaust ?, are all sport cats equal. I was looking at miltek or apr.
Thanks !
