In your opinion Mike do you reckon the downpipes are restrictive on these engines? I believe the cats are here. Ive seen catless downpipes for sale by Miltek.

Yes the cats are obviously restrictive and a way to get some power. Other issues for these engines is heat / cooling. With the turbos nestled into the V of the engine they can get quite hot. Once you start increasing the power then they get even hotter so when looking for big power this will need looking at.

Doug very rarely comes on here anymore.

And I think the RS6 has a single small charge cooler.

I wouldn't be surprised, most Audi S and RS turbo'd cars produce more power than quoted by Audi.
Shame about the b7 rs4 then :D
