I'm just heading towards Stage 2. Got a Revo Intake, Milltek catback (which sounds ace and not droney at all). Going to add the Milltek downpipe with race cat. Mounts, I'd stay away from the cheap rubber type mounts. I had the Powerflex one, then about 6 weeks later binned it and went Vibratechnics. Expensive, but worth it.
After downpipe I'll likely do fuel pump (was looking at Loba) and somewhere inbetween Helix clutch and LUK flywheel. As I can't fit em myself, I just get the garage to get them in and turn up for fitting.
