This was such an easy upgrade thanks to this writeup. Not intimidating at all! I didn't end up removing any bottom covers past the large aluminum plate. The last 2 plate bolts were under a plastic cover but it was flexible enough to get my hand and a wrench in there. I was done in about 90 minutes.

Best part? No leftover bolts! Haha

The Active Autowerke exhaust sounds amazing and the BPMSport stage 2 tune took care of the CEL that was thrown about a week later.

Thanks for the DIY!
