Hi, I have 2015 435i gran coupe and i recently noticed that my dual exhaust (stock, m package model) is not working properly. smoke only comes out of the right side of exhaust pipe, and when i place my hand on to the end of left exhaust, i don't feel anything when i start up the car (cold start).

Is this normal? or is it something serious and i need to take it to service centre?

Please if anyone knows anything about this. please tell me.

currently I'm living in canada which has cold winter.
