Yeah, the guy at Magnaflow is wrong. I took my angle grinder and chamfered the down pipe and it slid in the cat part, very tight but that is good. I will likely get it all bolted together and run it down to my friend's shop and let him weld it up. Pretty poor tech support. I'm also going to let my buddy do a better job on the heat shield welds which aren't that good.
I'm going to put a Flowmaster 40 series 3" in dual 2.5" out that I have laying around and probably dump it out the side with dual pipes ahead of the rear wheel to save a bit of cash for now.
