Hi all,

So I finally got around to getting the oem exhaust done to my e90 and absolutely love it. Absolutely the best bang for your buck!

Curosity is getting the best of my though...so my question is has anyone gotten the oem exhaust mod done plus deleted their secondary cats? I'm not to familiar with the difference between first and secondary or primary for that matter?

Anyone have any experience?
