Muffler was the correct length but with stock Cat 2 1/4" converter, identical to stock exhaust pipe. This muffler must have a 2 1/4 ID at the inlet and outlet. Both had an outside diameter of 2 1/4 which made it pointless to install a muffler I'm sure it would have been a good muffler but with the wrong size ends and the Revains auto test said it would fit the sizes!
