S3 Downpipe and Sport Cat – Questions

Hi guys,

I’m currently thinking about going from Stage 1 to Stage 2+ on my S3 and this looks even more likely as Revo have now confirmed that I can run Stage 2+ software with just a downpipe and sport cat + OEM catback system, rather than going for a full turbo back system. They say that the OEM catback system, is pretty good and not that restrictive.

So I’m looking at either the MV Sport downpipe and cat which mount straight to the OEM catback system, or a Milltek downpipe and cat and use a reducer to connect it to the OEM cat back system. 2 questions really:

1) Has anyone run the above setups at Stage 2/2+, how did you find them?

2) How hard is it to fit the new downpipe? Looks like it could be a nightmare of a job and you have to disconnect the prop shaft? Any guides anywhere?

Thanks guys

Cheers mate. I'm pretty sure on the S3 you don't need a reducer? Might be wrong, Ill check with MV Sports.

Also I've heard that the prop needs to be disconnected but not seen about the subframe, you sure about that?

Thanks!

I don't think the different between 2.75" and 3" is worth the extra for the Milltek? Also, Milltek have advised me not to run their downpipe with the OEM catback, where as the MV Sports system is designed for this from the word go?
