M5 F10 exhaust question...and warranty.
Hey all,
I know that most people poo poo Dinan, but are they still the only tuner that will not void the mfg warranty? I really don't want to own this car sans warranty, so any possible trade offs (unless they're major) will be worth the price of staying under factory warranty umbrella.
Thanks in advance for any info...
