I need help finding a muffler that connects to the cat, has a single opening on both sides in the center, im sure you already know that though. I'm in the process of replacing my rear cat as well with a Magnaflow Car-Sound number 94007. I wanna know if the shop would get this to fit(dont have the right tools to do it myself). I did the application finder on the car-sound site and it said the 94007 would go with my 93 5.0L. My current one has a crack in it, I put my hand over it and could feel the rpms, haha. Any help would be appreciated!
