    Yes it will, the turbo will spool up much faster, as well as help getting the heat out better.

    I think the only company that do a 3" DP that goes into the twin-cat assembly (assuming S3 is same as LCR) is Piper but this may not be a direct fit.

    3" Downpipe - Direct Replacement (uncoated), Piper Exhausts Online Store

    Most companies offer a 3" DP & Race-cat/Decat combo as it flows a lot better. IMO there's no point in keeping the OE Cat's, may as well go for the combo and then a cat0back when money permits.

    Yes Revo will charge you again mate... plus you need a little bit more than a downpipe to run stage 2
