Built specifically for the 2020-2022 Shelby GT500, the MBRP S7219409 resonator bypass replaces the factory mid-pipe resonator with a straight-through 3-inch section, freeing up exhaust flow and letting the supercharged 5.2L Predator V8 breathe and sound the way it was meant to.
T409 stainless steel construction. T409 stainless resists the heat cycles and corrosive exhaust gases that degrade mild steel over time, keeping the bypass looking and sealing properly through years of hard use.
3-inch diameter throughout. The full 3-inch bore maintains consistent flow velocity from the headers back, removing the restriction that a factory resonator introduces. Less turbulence in the mid-pipe translates to a more direct exhaust note and reduced backpressure across the RPM range.
Direct-fit installation. The bypass indexes to the existing mounting points and flanges on the GT500 exhaust system. No cutting, welding, or custom fabrication is required, making this a straightforward garage install that pairs cleanly with factory or aftermarket cat-back systems.
