No idea on how much downforce, but I'm somewhere between 3200 and 3300lbs with me and half a tank of gas in the car- Casey had it weigh in at 3315lbs when he did my corner balance, but the car has lost some weight since then (and it was done with the stock 19s on the car, not my apexs)

Too much back-pressure from the prototype exhaust I had on.

I swapped exhaust the day before I was going to take it in to get looked at, and figured why not clear the codes and give it a shot. It pulled all the way to redline and didn't throw any codes. I've tracked it 2-3 times since then and zero issues.

Were there any other problems with too much backpressure? Any engine damage or harm?

Not that I know of. My friend that is a bmw master tech thought I bent a valve or something, which was causing the error code, but there is no way of knowing unless we take the engine apart. Considering the car is running great now with no issues, I don't see myself taking it apart until I do rod bearings.

I'll let you know if anything shows up in the future

Could have sworn I replied earlier but just noticed I didn't.

Casey at Racewerkz had a lot of stuff left over from their shop car. The lexan windows, carbon doors, SPL components, differential, and rear wing are all from that car
