Ive come to the conclusion that to enable me to have the REVO stg2 on my S3, I`m going for the downpipe and sports cat instead of the full TBE. I understand the MV Sport can be fitted with no mods etc, but found the blueflame DP & sports cat today on E-Bay for £400 , is this a straight swap too? does anyone have this option? (mated to the OE cat back factory system) im wondering what sort of figures you made and how it sounds?
thanks
