Ok with a knock issue it wont be apparent until over a higher RPM or wont do much damage because it wont be a big issue until a Higher RPM, it could have been a bad batch of gas, it wouldnt be the first time. I dont know what are good gas stations in the US though. I would suggest a reflash back to stock base map, and return it for warrenty work at your local dealer they cant say it was caused by your exhuast but they could blame the AP so unmarry your AP and limp your car back to the dealership at under 3000rpm to be safe and not cause any more damage either that or have it towed there. depends on how bad the knock is. have them check it out and fix it..... best/cheapest solution. I bet you had a detonation problem with bad gas and then when you punched it it caused knock damaging your engine.... just a thought
