Exhaust smoke problem N54 335i

romeo519 · 04-25-2014, 03:02 PM

My current mods are AFE dual Intake, synapse BOV, AR Design downpipe, Cobb stage 2 aggressive LT, BMS oil catch can. After having the Downpipe installed and cobb stage 2 aggressive 2 weeks ago. Every now and then while driving, heavy smoke comes out of the exhaust for about a minute or two then it completely stops. This occurs after every half hour to an hour of driving around? I'm running 94 Octane from Petro... Is this normal ?
