Downpipe Reducer?


Registered User
Hi Guys, I have purchased the Militek De-Catted Downpipe, I want to fit this to the stock exhaust set up on the S1. Militek have advised me that I need a reducer but they are unsure of the stock piping size.

Does anyone know what the stock diameter of the exhaust size is??

I know the downpipe is a 3inch, so I need a 3inch to ....... (stock sizing)

Any help will be appreciated
