SIP Performance Pipe for T5

My T5s completely standard except for a HP4 flywheel...the original exhaust is now well rusty and needs replacing. Im thinking of buying a SIP performance exhaust…is there anything else that will need changing to suit this set up…?

cheers…much appreciated [:dance3:]

Cant help you with the tuning bit, but Id like to know if that fly-wheel is worth a look. I was thinking of getting one and you seem like the bloke to ask, did you fit it? could you notice much difference before and after fitting? does it affect 2-up scooting?
Sorry I couldn`t help with the other bit, any help on the fly-wheel would be great! Cheers [H]
