x2 on stock. If the chassis was stretched to a longer wheelbase, then it would've been cut someplace and extended with a piece of straight pipe, but that would be it. My guess is that a Class C with "21" in the Model Number would be on a stock wheelbase so nothing modded. FlowMaster (flowmastermufflers.com on WEB) used to sell "CAT Back" systems. Unbolt at the outlet of your catalytic converter and install new from there back using stock hangers. I put one on a much older E350 we had and it was nice. A little loud but ran cooler and more power. Might have bought 0.5-MPG but that would have been max. I think Gibson has CAT-Backs, maybe through Summit Racing. Not sure about this but the Bank$ $tinger system is a CAT-Back also.
