After the headers, not too bad - after the secondary cat delete, yes. I do not mind it. I was told by a friend it sounds like a modded E46 M3. I don't know if that's good or bad - considering it still sounds like a BMW and not a Honda, I'd say good

Thank you! They've stayed that color after over 3K miles.

Emissions has no concern with these, provided your state is NOT CA, where they are crazy strict with visuals.

Very nice 
Can't wait to see your results Tom Droze, I too have the N51 |
Thank you!

I predict something like 235-240whp based on intuition.
Which tune will you do: a off road header tune or a typical manifold only tune? Will a tuner like AA allow header tune on this? Because Header tunes differ than just turning off the CEL, wonder if the 300 CEL can handle it...

Yeah, I understand what you are saying. Either way, I'm very happy over the gains, performance and mainly low to mid end torque. I'll for sure update when I get a proper dyno done as the car sits.
I did not need the off road tune, as per my research this is mainly needed for catless headers. It was their standard tune, with some feedback from one of my datalogged interstate runs at WOT in 4th. I did note of the header mod to AA as well as it reflected in the data I've logged, then sent back to them for a second, custom tune.
