You could do ebay headers (any headers really) and dump that into OEM E46 M3 euro section 1. That takes out the first muffler and puts two cats in instead.

I sent the guy a lengthy PM asking for some info. Will report back if he responds, and I also invited him to join here and possibly discuss with us directly.

Jack is usually very responsive and has great data. 200 cell cats most likely pass but they'd need to be smokin' hot and nothing else could be wrong with the car. Not sure about the CEL due to O2 sensors etc. that has been discussed.

I'm really looking forward to his input.

Wrap em in header wrap and do a few 0-80 blasts right before going in for testing.

Is it worth it? 400 cell wouldn't really make that much of a power difference when compared to 200 cell, and you wouldn't have to do anything like wrap/heat.
Or am I wrong?
