So I've had my F90 M5 for almost 5 years and have only gotten my car serviced at the dealership where I bought it from (ran a great promo on prepaid maintenance when I bought it). I'm looking to add some more character to the car like Eventuri Intakes, Evolution Racewerks Downpipes, and a tune. I've been wanting to do this for some time but I am hesistant as it will void my extended warranty which is up to 6 years/100,000 mile warranty. I've also heard some horror stories of peoples engines blowing up and what not from a tune and downpipes which has kind of steered me away all these years but then again these people are trying to push the car wayyyyyyy past its limit. I feel like just saying f*ck it and doing it anyway, but I can't seem to drop the hammer on this thing. Any advice from anyone on what I should do and what their experience has been like with dealerships, the cars themselves (maintenance and reliability wise), etc after the intakes, tune, downpipes is greatly appreciated!
