Ok, took off my entire exhaust setup (Highline, cats)
and went back OEM but left my ebay headers. just couldn't take the noise anymore...I guess that comes with age.

anyway becoming a member on the and not actually owning a M3...still I want one in the future.

I came acoss a very useful tread about 02sim more than what I got from e46fanatics. sorry!

so here is my DIY and I have to see the true outcome...but I have read on the M3 forum that everyone is passing emission and no SES.

this is all me! but please remember *OFFROAD USE ONLY!*

Props to mills84 on
