    Some context would also be useful...

    Stats are irrelevant on OE kit as they are 'enough' for the standard cars they are fitted too...

    Gains are to be had replacing them wit aftermarket... S3 DP's are particularly rubbish....

    Am I being stupid or has the standard cat been cut out? And I think I'm correct in saying that the bam dp has a lambda pre and post cat?

    Not sure what's going on at the end of the dp either? Cut again, or are they all twisted like that?

    Ah I see! So the cat isn't actually part of the dp! And looking at that one, I can see why these are changed out! They look very restrictive! And looks like a bam one with lambdas pre and post cat, one on dp and one on which looks like a link pipe with a cat in it!

    Thanks for that image tufty!
