Excessive smoke after catless DP

[AWF10M5]

I?ve has catless DP for a month and half now put about 5k miles on them.

It's gotten really cold and I? have noticed when idling or at a light there is smoke when car is idling.

Doesn't matter if car is warm or not. Just white smoke always behind the car I?t smells like combustion and is white

I? believe my 335 catless did same
Thing but my friends m6 catless does not do this.


Do you guys think this is a big problem?

After monitoring it better realized it's normal catless smoke. When car is warmed up it's just little smoking from exhaust pipes.

One of the main reasons I didn’t do DP’s on the car.

Stop being paranoid ! Your car is fine.

Mine never smokes but does stink especially at drive thrus (McD's and Burger King employees hate me).

Let us know if you find an issue with your engine or exhaust.

Realized the smoke is normal catless smoke. Massive smoke was a understatement

After warm up car smokes but so does every other car when it's 33 outside here

I?f you guys see videos of m5/m6 in cold climate that are catless you'll see this happens to them too
