Stainless Dual Outlet Muffler, 1-In / 2-Out Straight-Through Design (409)

Single-In, Dual-Out Straight-Through Muffler

A 409 stainless dual-outlet muffler with a single 3-inch inlet and dual 2.5-inch outlets — a true 1-in, 2-out straight-through design. It delivers a deep, aggressive tone with minimal cabin drone, and because it flows straight through it frees up exhaust flow instead of choking it like a stock or chambered muffler. A clean way to split a single pipe into dual exits.

Built to Perform
Heavy-gauge 409 stainless construction, an advanced flow-through design, and all-welded craftsmanship stand up to the toughest conditions. The 100% reversible design adds flexibility, and a high-temperature filler with a tubular stainless liner keeps the sound consistent and the muffler lasting for years.

Why Choose B2 Fabrication?
Our mufflers go head-to-head with MagnaFlow, Corsa, and Borla on craftsmanship, thicker materials, and fit and finish — at a direct-from-the-builder price. You get an aggressive yet refined tone while keeping excessive cabin drone in check.
