Because the 2001 GMC C-3 Truck is a limited version of the Sierra model, Magnaflow does not list a fitment for that vehicle.

The MagnaFlow Muffler, # MF12468, you have referenced is a universal muffler that is 5 inches tall and 8 inches wide and 24 inches long. The muffler body length is 18 inches.

The fitments they do list for similar trucks like the 2001 GMC C-3 are the 5 inches tall and 11 inches wide and 28 inches long with a muffler body length of 22 inches.

They would be the MagnaFlow Muffler, # MF12568, which has a 2-1/2 inch inlet and outlet. The MagnaFlow Muffler, # MF12569, which has a 3 inch inlet and 2-1/2 inch outlet and the MagnaFlow Muffler, # MF12599, that has a 3 inch inlet and 3 inch outlet.

To make sure what fitment you would need is to measure the size of your muffler on the truck. Measure the height, the width, the overall length from end of inlet to end of outlet and the body length of just the muffler. You will also want to measure the overall diameter of the inlet and outlet pipes.
