N10 code with single exhaust?
My RPO sheet includes N10, which I think means dual exhaust. Yet, my GTA only has a single exhaust tip out the back.
I'm the third owner of this car. The guy I bought it from said it had flowmaster on it. (I'm not sure if he was referring to a muffler or the whole exhaust.)
Would I be correct in assuming the flowmaster killed my dual exhaust, making it single? If this is the case, wouldn't I be getting less horsepower?
Thanks,
Bill

Not sure about the N10,but It may mean dual cat......also if the previous owner put a regular muffler on it not a cross flow style that would explain the single tip....hope that helps.

'Dual' in that case, means 'dual cat exhaust' not 'dual exhaust'.
Its still a single exhaust system, but with two cat converters instead of the usual one cat.
