Well, you guys must have a magic touch. After fighting with it for 45 minutes, driving up on some ramps (which are now torched), driving up the rear passenger wheel up on nine inches of stacked 2" X 12", it still would not come out. I removed the spare and the shock. It just wouldn't go. The step tubes were also in the way, or the big a$$ 20" tire. Finally, I cut off about ten inches of the tailpipe and it slid through. I have no idea how you do it, but after studying it and twisting it for eternity, I said screw it. If, and I stress IF, I ever put it back on, I'll add a tail piece. I doubt it will ever go back on. I have done several systems on my past trucks with the same idea, but the stock systems eventually went in the trash after I sold the truck. Besides, after torquing down the clamps on the MBRP and putting a crimp in the pipes (even if the clamps fell off)the pipes will never come apart. It seemed I tightened down on the clamps forever before they snugged up enough to prevent the pipes from rotating or pulling apart. Now, I doubt I'll be able to put in a muffler delete without a sawzall. Darn. I ran the truck down the road with no pipe after the convereter. It sounded sweet - and not loud at all. After running a dual Roush Off Road system on my 2007 F-150, this MBRP sounds very tame - too tame. I wish I had gone with the muffler delete.
Anyway (as I jaw too much), thanks for the input guys. maybe next time I will be able to pull it off.
