My current exhaust is stock with no muffler off the cat just under the bed i was wondering if i am able to just buy a pipe which will fit the clamps on the cat to extend it to the end of the truck what is the size of the outlet of the cat
thanks alot

Stock exhaust on these is 3.5" od.

Yup. Keep in mind the stock downpipe is only 3 inch.

What year is your truck? My 01' doesn't have a cat. Just muffler under the bed.

Try Don't index this page and email jhack for what you need. They used to list the pipe you need on line but I couldn't find it when I checked today. I got mine from them several years ago. (I guess the sponsors don't like publishing that url but click on it, it worked when I tried it.)

Weird, no idea what that is, maybe previous owner added a second muffler?

Just ditch the whole contraption. Nate from Performance Truck Products LLC - Diesel and Gas Performance Parts and Accessories can hook you up with the 17979 magnaflow 4" turbo-back 409 stainless system for $299 delivered. Sweet deal. I like mine so far. :thumbsup:
