So I have a 2016 Mustang GT with an MBRP "Race" 3in Catback and on an auto-start I saw a good man sized plume of white smoke blow out of each exhaust at ignition. I've smelled the gas (Not sweet) and checked fluid levels (Normal) and it has been about a week since the incident. Also did a few WOT pulls with my buddies GTO following me and he said no smoke was visible from the exhausts. Havn't seen it happen since. I did leave the car idling in the parking lot for 30 minutes that morning before work. At this point I'm assuming it just burned off all the excess gas ect that was being discharged for idling that long. Any other opinions would be appreciated!
