They may have to be taken out and cleaned manually, at which point I may opt for downpipes although I really love the sound I have right now and don't want it to change much. We'll see. I can use BimmerLink to clear the code if it's bugging me, and the steering wheel covers up the CEL...so not a dire situation. It's not something that poses a danger to the car, though it's lost some performance and is now faster than only 95% of the other cars on the road, instead of 99%. There's a first-world problem for ya.

And to take this a point further, one of my best friends always says, "The chance of 2 cars with 500 or 600 HP pulling up at the same light simultaneously is pretty slim."

That sounds like a good plan. Let me know how it goes!
