I have 2000 Maxima and I damaged the muffler. I live in Minnesota, but the car has the California emisions. The Nissan dealer wants $550 to replace just the muffler as he says its a special emissions type and by putting a standard muffler on it may effect the computer. Does anyone know if this is true? Thanks

Yes and No. The computer can read signals from the rear O2 sensor and therfore trigger a CEL. I have never heard of this being true for the muffler. Your best bet is to call outside of your town/city and get prices.

I did install a normal (non Calif.) muffler. Since the O2 sensor is in front of the cat, different mufflers shouldn't affect the computer(?). But I'll find out. Thanks

I have never heard of the muffler for a CA car being different than the others, my first thought would be RIP OFF dealer
