Question: What is the outside diameter of the exit pipe of the muffler?  I am asking because my current muffler and tail pipe is welded together with no clamps. I am not sure if the pipes are such that I can weld the new muffler and old tail pipe together. Some Advertisements tell me a different part number is required. I just do not know why as the mufflers look the same. The other muffler is $20 more expensive but does not have a tail pipe included.Hammer Head / Mar 08, 2021
Hi Mike, The part number WK21456, is with production date After Jan-24-2000 onwards fitment (sticker at the driver side door jamb of your Jeep). The exhaust system you have might have been upgraded already before by the previous owner of your vehicle. I have included a link below where you have to enter your vehicle application and it would show a diagram of your Jeep's exhaust system complete. http://www.brexhaust.com/catalog.asp You can also call Walker exhaust to confirm details, 800.325.8886 (for the other part number 21456).
