Super 40 Series Muffler 3in Center In/2.5 Dual

The Super 40 Series Muffler 3in Center In/2.5 Dual by Flowmaster is engineered for automotive enthusiasts and mechanics seeking a balance between aggressive performance sound and street-legal operation. This dual-outlet configuration is ideal for vehicles requiring aggressive styling with controlled noise output—whether you're building a street cruiser, performance daily driver, or restoration project. The 3-inch center inlet transitioning to dual 2.5-inch outlets provides a clean, compact installation footprint while maintaining structural integrity through extended use.

Flowmaster's Super 40 Series utilizes a chambered, tuned design that reduces backpressure while delivering a distinctive exhaust note characteristic of high-flow performance mufflers. The 3-inch-to-2.5-inch dual configuration allows dual tailpipes for visual impact without requiring extensive frame or body modifications—a critical advantage when retrofitting larger displacement engines or upgrading exhaust systems on tight-tolerance platforms. At 13.7 lbs, the muffler's weight distribution is optimized to minimize sagging and vibration transmission to the vehicle chassis. Internal baffle design manages exhaust velocity transitions smoothly, reducing drone and maintaining scavenging efficiency across RPM ranges.

This muffler benefits mechanics and owners upgrading mid-size V6 or V8 platforms where single 3-inch systems prove inadequate but full 4-inch dual systems create fitment conflicts. Installation requires basic exhaust work with standard hanger hardware; the compact dimensions (16.65 x 5.8 x 21.1 inches) fit vehicles with rear-mounted fuel tanks or tight undercarriage geometry. Verify mounting clearance and tailpipe routing before purchase, as dual 2.5-inch outlets demand specific exit strategies. Compatible with custom exhaust fabrication or bolt-on performance kits utilizing 3-inch piping.
