MBRP Muffler – Universal Fit – Aluminized Steel – 3-Inch / 2.5-Inch

Free shipping on this MBRP 3-inch / 2.5-inch universal aluminized steel muffler.

Engineered for fabricators who need predictable flow and reliable material performance, this MBRP universal muffler uses aluminized steel to deliver stable thermal behavior and dependable corrosion resistance. The dual‑diameter configuration (3-inch inlet, 2.5-inch outlet) supports a wide range of custom gas and diesel applications where sizing transitions and controlled tone matter.

The straight‑through internal core maintains exhaust velocity while reducing turbulence, giving builders a consistent foundation for custom systems that require balanced sound output and efficient flow.
