Muffler 5in Inlet/Outlet Stainless

The Muffler 5in Inlet/Outlet Stainless from Vibrant Performance is purpose-built for serious enthusiasts and mechanics seeking refined exhaust flow with minimal acoustic signature. This race-grade muffler suits custom exhaust builds, street performance applications, and restorations where sound control matters alongside power delivery. Whether you're engineering a street rod, turbocharged platform, or performance daily driver, a quality muffler with matching inlet and outlet sizing ensures seamless integration into your exhaust system while maintaining backpressure balance.

Built from stainless steel, this muffler resists corrosion and thermal stress far better than mild steel alternatives, extending service life in harsh underbody environments. The symmetrical 5-inch inlet and outlet ports eliminate flow restrictions and simplify custom piping routes, while the compact 5.75-inch diameter body fits tight engine bay and frame configurations. Stainless construction also provides superior sound dampening characteristics—the material's density and finish quality absorb higher frequencies, producing a refined exhaust note rather than a hollow drone. At just 1.8 lbs, the lightweight design minimizes unsprung mass without sacrificing structural integrity or thermal performance.

Mechanics and fabricators favor this muffler for custom exhaust systems where standardized, bolt-on components fall short. The matched 5-inch port sizing accommodates both mild and aggressive exhaust manifolds, making it versatile across engine displacement and power levels. Installation requires basic exhaust clamps and hangers; ensure adequate clearance from brake lines and fuel systems during routing. This is an individual muffler unit sold separately, allowing builders to design complete exhaust architectures tailored to their specific platform, budget, and performance goals.
