Looks like a cannon? lol...

I didn't think they could give you a ticket for the SIZE of an exhaust...

I have N1 Dual. Granted, it's not cannon-style like the single, but I've personally never run into any problems with cops.

However, I found these laws applying to exhaust:

(4) No person shall drive or operate a motor vehicle propelled by an internal combustion engine equipped with a muffler, the exhaust outlet of which has been opened or widened.
(5) No person shall drive or operate a motor vehicle propelled by an internal combustion engine equipped with a muffler or exhaust system to which is attached any device which increases the noise of the expulsion of the gases from the engine or allows a flame to be ignited from the exhaust system.
