Hmm, I'm confused. Haha.
I'm actually contemplating on 2 different solutions.
1) Get my downpipes fixed and *cross my fingers* till something happens.
2) Try bringing it to the dealer and fix the problems before installing downpipes.
The problem with option 2 is, even if i bring it to the dealer, as what they always do best, they would come up with excuses saying that its normal.. blah blah blah. Also, the sound is not obvious when engine is warmed up. Therefore, I'm thinking if the engine would to throw a code, it would be much better as the mechanics have no choice but to do smth. If it doenst throw any codes, they can deny my complaint (i suppose thats what BMW always does?)
