Make sure to not mess that clamp up. This is the clamp for the N10 dual cat exhaust that everyone calls the "Hog Clamp". It looks like a V-Band clamp but I don't think it exactly is one. It's also for 2.75 inch pipe. The wider cutout at the top left of the "Hog Clamp" indexes the two mating pipes to each other.
I posted the above in another thread. This is the type of clamp you need for a 1989 to 1991.5 N10 system.
