Downpipes and modified exhaust exhaust installed. Happy to report zero odor, sounds very nice (low grumble-very sporty-just a bit louder than stock) and ridiculously fast. Basically spins the tires at will. First run from standing still in D3 she spun the rear end out shifting into 3rd in MDM. :-)
Very happy.
I need to note that I used the term "BMW Performance" to describe a few intended upgrades. They are not BMW parts and not represented to me as such. They are modified parts (tune is a totally custom tune) that are the basis for the mods. They are modified to be higher performance. Again, not sold by BMW or represented as BMW parts. I frankly was expressing that we were modding parts and not using aftermarket built parts. I never made the connection to "BMW Performance", the actual line of BMW stuff that is sold. My bad-foot in mouth.
