well, don't they usually just stick a thing in your tail pipe and look under the hood? if you hit the switch and go to regular stock exhaust, it should be stock and pass. when you hit the switch it closes the pipe to the stock exhaust and opens a pipe that has no restrictions at all. so daily driving you have stock exhaust that's not hella loud, then at the track you have it sounding like a mean *** race car....
another question i'd have is the tune. wouldn't the air/fuel ratio be off? unless some how you could hook up a little portable tune device (i think my friend has one for his mustang) but if you do have that, could you hook it up to the switch that does the exhaust change (so that it changes the exhaust and tunes itself at the same time) and could the car be in motion when you change the tune? or would you have to park it first?
