Flowmaster 72579 Flow FX Muffler 3" Center In / 3" Center Out Oval Body Stainless Steel

The Flowmaster 72579 Flow FX Muffler delivers a moderate performance exhaust tone for enthusiasts who want a deeper, more traditional sound without the aggressive punch of a chambered muffler. With a 3-inch center inlet and 3-inch center outlet, this muffler is well-suited for large displacement gas engines running single exhaust configurations.

Inside, a large-diameter straight-through stainless steel perforated core is wrapped in high-temperature sound absorption material, producing a deep, mellow exhaust note while improving exhaust flow and reducing back pressure. The reversible internal flow design allows installation in either direction to best accommodate the vehicle layout and pipe routing needs.

Key Features:

• 3.00" center inlet / 3.00" center outlet configuration
• 5" x 11" x 22" oval body — compact profile for tight installation spaces
• Straight-through perforated core design for improved exhaust flow and performance
• High-temperature interior sound absorption material for a deep, mellow exhaust tone
• Fully MIG-welded 409 stainless steel construction for long-lasting corrosion resistance
• Flow FX logo embossed on both sides of the case
• Reversible flow path for flexible installation orientation
• Universal fitment — not a direct bolt-on; some adaptation may be required

The Flowmaster Flow FX 72579 is an excellent choice for anyone seeking show-quality performance muffler aesthetics at an economical price point, in a space-saving oval body design.
