Anyone have an idea as to where a person can get a replacement crossover pipe for an M Body that doesn't have these two idiotic pre-cats welded to them? I own 2 M Body cars, 1 Chrysler, 1 Dodge, both 1987, both have these mutations on them. The Chrysler Fifth Ave. is starting to experience the left mutant beginning to clog and restrict flow, and actually got so hot at one point after sitting for awhile, that after it ran for a few minute at cold idle speed, the cat was actually glowing red!! I want to get rid of all four of these puppies, and a replacement crossover pipe without the cats would be a welcomed change. I've looked everywhere for one of these, and no luck. I'm about ready to go to a custom muffler shop and have a custom bent pipe made for them if possible. Whatever the case, these have got to go!
