Magnaflow 2006 Dodge Ram 1500 5.7L Direct Fit Converter

Built for the 2006 Dodge Ram 1500 with the 5.7L Hemi, this MagnaFlow direct-fit catalytic converter (part 5451711) is a bolt-on replacement that matches the factory exhaust routing. No cutting, no welding, and no guesswork on whether it lines up.

MagnaFlow uses 16-gauge 409 stainless steel tubing on this converter, which holds up against the heat and moisture that break down lesser materials over time. The mandrel-bent tubing preserves the same bends and geometry as the original part, so exhaust flow stays smooth and your truck maintains its fuel economy. The spun body converter uses a single laser fusion weld to closely replicate the OE design and minimize leak potential. MagnaFlow's metrology department uses 3D scanning during development to verify dimensional accuracy against the factory part.

This converter is CARB-compliant and legal in all 50 states including California, Colorado, New York, and Maine. The kit comes with a Torca AccuSeal clamp and two O2 port plugs, plus the necessary hardware and gaskets. That means you can complete the job without sourcing extra fittings or reusing old corroded hardware.

If your 2006 Ram 1500 has a failing converter or needs to pass an emissions test, this MagnaFlow unit gets the job done. The 308 stainless MIG welds and precision-stamped collector are consistent with what you would expect from a well-built replacement converter at this level.
