Smithy Muffler - 2.25 Inlet 22.0 Long

The Smithy Muffler - 2.25 Inlet 22.0 Long from Patriot Exhaust is a direct-fit performance silencer engineered for builders and mechanics who demand proven, quiet exhaust flow without compromising mid-range torque. This steel construction muffler addresses a critical need in custom automotive builds: balancing acoustic suppression with exhaust scavenging efficiency. Whether you're tuning a street cruiser, restoration project, or light-duty performance vehicle, this 22-inch unit fits tight engine bays while delivering the straightforward engineering that seasoned fabricators trust.

Built from welded steel and finished in protective blue paint, the Smithy muffler uses a chambered design that dissipates sound energy through tuned internal passages rather than restrictive packing materials. The 2.25-inch inlet and outlet diameter maintains flow continuity with common header and pipe configurations, critical for preserving scavenging pulses that signal the engine's induction cycle. Its compact 3.5-inch outer diameter and 22-inch length allow mounting in tight packaging—ideal for mid-engine layouts, compact frames, or systems where hood clearance is limited. At 6.42 pounds, the steel construction trades weight for durability and heat resistance, ensuring the muffler withstands sustained exhaust temperatures without deterioration.

Mechanics restoring classic vehicles or fabricating custom exhausts will appreciate Patriot Exhaust's straightforward engineering—no complex internal baffle stacks to clog or corrode. Installation requires 2.25-inch piping and standard U-clamp or band-clamp mounting; verify inlet/outlet alignment before welding to avoid thermal stress. This muffler performs best in applications where total system backpressure is managed (header design and pipe diameter matter as much as the silencer itself). Check clearance dimensions against your transmission tunnel and chassis before final placement; the 33.8-inch overall length demands careful routing in compact builds.
