Wasnt really considering DPs for this car before, but id love the power and sound. Would the catted DP's give me a CEL or any codes at all on a early 2010 135i? I currently just have a JB+ and a chargepipe/BOV setup, also a maddad midpipe/axleback exhaust. Since these have the oem O2 bungs would I just have my sensors plugged right in to them no problem? Hows the install/setup?
