schmiedmann makes some nice headers, with optional 'section 1' (M3-speak) piping with high flow cats. looks like a decent option, but i'm not sure the cats will get hot enough to do anything.

I have the ebay headers with DEI Titanium wrap on my ZHP. They make a nice difference across the power band and sound great on the car with the stock ZHP cat-back. The CEL is the only downside...
^^ that's stock muffler?? I'm doing this soon and...damn maybe I won't also do a muffler.
This is the way to do it. Code out the CEL and you're good to go until you have to pass emissions.
If you need to pass emissions like I do, Google area 74 o2 simulator. It's effectively saved the N55 crowd from the government nonsense. Works on any vehicle.

Thank you! I've long debated replacing the stock primary resonator with an x-pipe, but with the sound as-is...
Good luck with yours, post a video after it's done!
Header install delayed. Basically pulled every muscle in my body doing misc work on my car and a friends. Headers install next time I have energy! I'll make sure to post a clip.
