Tim that sucks! You'd figure an exhaust wouldn't even be considered for something like that. That's like saying your engine blew because you changed your valve cover color.

Only thing I could understand is that usually in the event of mods a majority (not saying you) of the people will be thrashing the car because they modded it for that reason. They should not put this on every driver, however, specially when the car is used. But, how many police officers make the distinction between the driver and the sports car in a sea of normal/family cars? Stereotyping is bad for many reasons. Then again I have yet to find a dealership that doesn't overcharge/lie to people who don't know anything about cars or try to cop out on warranties.

That's what you get when greed becomes people's motivation instead of happy customers and long lasting company-public relationship.
