As there is no gains, apart from noise, by going cat back, is there benefit of just replacing downpipe and cat, and utilising the existing pipework from cat back?
Downpipe and sports cat, mated to OEM centre and backbox?

Yes, I had this setup on my car for 6+ months and had massive torque gains (50Nm!).
Ultimately it does restrict top end power but you get 90% of the gains this way.

Excellent, sounds positive.
What model car were you running it on?
And what set up did you have? For example, does the Milltek come with a reducer to fit the cat back OEM pipe, or can one be specified from Milltek as an off the shelf part?)
Did it drone at all?

Joe - Just replied to your other thread.
Downtothebone - Have you just got downpipe and sports cat? (whats the Cat back set up you have?)

facelift S3 (3dr)
I picked up a 100 cell MV Sports downpipe from a forum member and my garage added a reducer to suit.
Definately no drone - you still have the OEM centre box afterall.
