I'm sure this has been asked a bunch of times so my apologies for asking what may be an obvious question. Just looking for a definitive answer. Have a leased 2014 335 m-sport. Want to install intake exhaust and burger tuning. I know the burger is definite red flag but does the exhaust and intake void the warranty. One could always easily pull the burger out for routine maintenance even the intake for that matter... My plan was to put everything back to stock before returning the car. Then sell the aftermarket parts. I'm totally against the m-performance exhaust - can't see taking a hack saw to my stock pipe.

Only if it is the direct cause of fault or malfunction during a warranty claim. Otherwise a dealer could care less.
