how many on here have fitted milltek downpipe and sports cats on to standard systems, thinking it was all that was required to go to a stage 2 map. this is the email I received from milltek when I enquired about buying a reducer on to standard system.
Many thanks for your email.
With regards your enquiry an adaptor is not available for the installation of the high flow downpipe and sports cat onto the OE system.
Due to the diameter differences and the restrictions within the OE system the heat build up within the downpipe and sports cat would cause damage and premature failure of the catalyst assembly, especially if used with additional hardware changes and software changes.
