Smithy Muffler - 2.50 Inlet 22.0 Long

The Smithy Muffler – 2.50 Inlet 22.0 Long from PATRIOT EXHAUST is a straight-through performance muffler designed for custom exhaust builds and street applications that require versatile inlet sizing and a compact length. This muffler serves as a drop-in silencing solution for fabricators, enthusiasts, and mechanics who are building or upgrading exhaust systems where noise reduction must coexist with flow efficiency.

With a 2.50-inch inlet diameter, it matches common exhaust tubing sizes, making integration straightforward for both single and dual-outlet configurations. The 22.0-inch length provides a compact footprint, which is critical when working within chassis constraints or under-vehicle clearance limitations. Its internally chambered design balances acoustic attenuation with back-pressure characteristics, ensuring optimal performance.

This muffler is ideal for street builders, restoration specialists, and DIY fabricators who demand modularity and compatibility in their exhaust systems. Weighing 7 pounds, it is light enough to minimize suspension load while being robust enough to resist vibration and resonance issues common in thinner-wall alternatives. The straightforward inlet design simplifies welding and slip-fit connections, reducing fabrication time without compromising structural integrity or long-term corrosion resistance.
