I think somebody has the N412 and N42 codes confused....
The N41 code is for dual exhaust which was standard on 340s.
The N42 code is for the optional chrome tips. Cars shipped to Carbafornia could not get the tips as they needed the turndowns as part of the
N97 Noise Reduction Package.
If I remember correctly, about the only cars that had chrome tips as standard equipment were the 67 GTX and the T/A and AAR cars.
