I don't see any great or even repeatable differences from cars with catbacks over these numbers. I've had cars with complete stock exhausts do better than those with catbacks. Last week I had a '12 with a full TBE which needed 10% more WGDC to hit the same boost targets as other stg2 cars did with a stock CBE.

You can be totally right. I'm just saying, replacing JUST the DP makes no sense. If you WERE to, then do the whole exhaust. Unless, someone can tune a stocker, then switch just the DP, then see if they can get more out... then how much they do, if they do, is it worth it. I would imagine no. but, I'm learning as I go along too!
