Exhaust/intake mod = instant warranty death?
Do all the people here with DCIs, catless DPs, and cat-back exhausts not give a hoot about their BMW warranty or do they remove these parts each and every time they get the car serviced?
I'm dying to get a coated DP and intake, to relieve the turbo's workload and move heat out of the turbocharger, but I'm not sure I am ready for a $16,000 gamble.
Just wondering what you felt about that.
