That really doesn't tell you the fine print. But depends on the dealer and problems you many get. They would love to use any opportunity to back out of an expensive fix. But really a cat less exhaust won't screw up stuff, it would be annoying loud.

But..... I would keep the stock exhaust, and slap it back on when it's time for service. Or whenever you get over the loud droning noise, or the black sut on the ground on start up. That's if you park your car at the same place all the time.
