Super 10 Series Muffler 2.5in Center/Dual 2.25in

The Flowmaster Super 10 Series Muffler 2.5in Center/Dual 2.25in is a universal stainless steel performance muffler engineered for builders seeking a balance between deep exhaust tone and efficient sound suppression. This dual-outlet configuration appeals to hot rod enthusiasts, street machine owners, and custom builders who want the aggressive presence of a dual exhaust aesthetic without requiring a full dual-pipe system. The Super 10 platform delivers Flowmaster's signature aggressive scavenging design while maintaining compatibility across a wide range of vehicles through its 2.5-inch center inlet and dual 2.25-inch outlet ports.

Constructed from premium stainless steel with a durable black paint finish, the Super 10 Series muffler features a compact 6.5 x 9.5 x 4-inch oval body measuring 12.5 inches in length, allowing for tight installation in many underbody configurations. Flowmaster's Delta Flow technology uses a patented chamber design that minimizes backpressure while optimizing scavenging pulses, resulting in improved horsepower delivery and torque across the RPM band. The aggressive internal baffle geometry produces the characteristic deep, muscular tone that enthusiasts associate with the Super 10 line, while the stainless construction resists corrosion and maintains its black finish through years of exposure to moisture and road salt.

This universal muffler is ideal for custom exhaust fabricators and DIY builders adapting high-flow systems to older trucks, muscle cars, and street rods where OEM fitment options are unavailable or incompatible. The dual 2.25-inch outlets allow plumbing flexibility—whether running both outlets to separate rear exits or merging them into a single tailpipe—giving fabricators multiple aesthetic and functional options. Installation requires basic welding or clamping skills; verify inlet and outlet dimensions match your existing piping before ordering. Weighing 6.9 pounds, the muffler integrates seamlessly into most custom applications while maintaining optimized scavenging flow for naturally aspirated and forced-induction engines alike.
