why don't you just buy a magnaflow muffler and have it welded on. what's the waiting list for, it's just a muffler how hard is that to make. I don't see any reason for them to do the whole after cat thing, the rear pipe is a decent size, and it's not restrictive.

What they need to make is the upper exhaust, that's where the restrictions are, especially with that flattened passenger pipe. Maybe an off-road catless version.
