Anyone of these will work. Are you going to stay with the single exit? Then get the single in/out. If you are going with dual tailpipes, then you need the single in/double out. I believe your stock exhaust diameter is 2.25", but I might be wrong.

You are going to need to get under the truck and take a look for yourself as to which configuration will work best for your application. It looks to me like 52455 or 52456 would probably be your best bet. Are the exhaust tubes lined up where they come in and go out, or are they offset?

That would make sense. I would replace the c clamps with new ones. You can get them in the correct diameter at any major parts store. That would also allow you to do the install yourself and not have to pay a muffler shop.
