I just purchased a 2013 328i xdrive with premium package and sport line. I'm curious if there are any BMW factory performance mods available that don't void the CPO warranty? M Performance exhaust--I can't find it on any dealer sites for this year? Any other tunes available to boost HP? Many thanks.
Does the m perf exhaust impact the warranty at all and any power gains or just better sound?
I ended up buying and having the m performance exhaust installed. I was on the fence and must say I'm very happy with the mod. It's just the right sound and fits the car's persona nicely. Not too loud but adds character.
Now hoping the m performance package comes out soon!
no... bmw performance parts do no void bmw warranty... there should be a suspension kit from bmw... that will add more attitude to vehicle ride characteristics
