Also how much should a secondary cat delete cost me? are there any diy guides on the 328xi e92.
couple of hundred miles should be set, popping depends on N51 or N52 and air temp. N51 only pop a lil even on a hot day, N52 will pop much louder.

both pop pretty loud with secondary removed, delete should cost around $100 by muffler shop, best way to do this is use mid pip from AFe.
