UPDATE: I reported last week that I got my mufflers attached. Here’s some pics of that. On my last jeep, I never liked the way I connected my mufflers, so I decided this time I would create a more secure setup.
To start, I select some ‘Cherry Bomb’ mufflers that were the smallest, least expensive ones I could find at my local Schucks store. Between the headers and muffler I added a short piece of flexible pipe, in part to provide a little flexibility and to turn the corner underneath the front cage mount. Behind the muffler, I connected a tube with a 50 degree bend and an angle cut at the very end. To the tailpipe I also welded a flat piece of steel with two holes so that I could connect the muffler section to the bottom of the tube show in the pics below. You can see that I drilled a holes and inserted studs, which I welded in place, so I could easily connect the mufflers.
