I had the Kline exhaust with 100cpi cats bolted on my 991.2 Turbo S last week and today I took it to the track.
Immidiately I could feel it wasn't pulling as before with stock exhaust. Maximum pressure I obtained was 0,8 bar against 1,2 bar before. I also have feeling for higher fuel consumption than previously, didn't meassure though. There was no CEL.

Anyone have a clue what caused this?

I plan to have the Cobb ECU flash when it arrives, or perhaps take the intermediate route via ByDesign.

BTW, the sound of the Kline is just perfect

Exhaust should not cause those issues. I would get it checked before the Cobb install. I have the Cobb tune and PDK Update. Definitely run the PDK Relearn in the trouble shooting section after the tune and update are loaded. Smooths the shifting out nicely.

It sounds to me like you have a boost leak somewhere. But that's just a completely off-the-cuff opinion. The exhaust shouldn't cause issues like that.

Dealer detected electric impulses to wastegates on both sides broken, mystery how that happened.
Hope to have it resolved very soon.

Would like to hear how they think that happened.
