Put stainless underneath it.\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA complete crossmember-back system for 1967–1972 Ford F-100, F-250, and F-350 2WD long bed V8 trucks with a side tank — 2.50-inch mandrel-bent 409 stainless, Super 44 mufflers, and every hanger and clamp needed to install it at home.\u003c\/p\u003e\u003cp\u003eFactory exhaust on these trucks was built quiet and cheap. This one was built to flow. It picks up behind your manifolds or headers and runs 2.50-inch mandrel-bent tubing all the way back, holding full diameter through every bend instead of getting crushed in the turns.\u003c\/p\u003e\u003cp\u003eEvery piece you need is in the box — tubing, built-in H-pipe crossover, two Super 44 mufflers, hangers, flat band clamps, and brackets. Flowmaster built it for an at-home install, and you pick the exit: straight out the rear, side exit behind each rear tire, or dumped behind the tires.\u003c\/p\u003e\u003cp\u003e409 stainless is why this system stays under your truck. Salt and heat cycles are what kill mild steel.
