MagnaFlow Performance Exhaust Muffler 11224 - Deep Resonant Tone

In this review the MagnaFlow Performance Exhaust Muffler 11224 is examined for drivers seeking a deeper, more authoritative exhaust tone without sacrificing flow or durability. The bottom line: this 4x9x14' oval stainless muffler is best for enthusiasts who want the classic signature MagnaFlow sound and measurable gains from improved exhaust evacuation. Its straight-through perforated core and two-stage packing focus on smooth tone and preserved exhaust velocity, making it a straightforward upgrade for many custom or replacement installations.

Key Features

• Signature sound: The 4 in x 9 in oval body is engineered to deliver a deep, resonating tone that is noticeable across the rev range without being obnoxiously sharp.
• Dyno-proven performance: Extensive dyno testing supports that the muffler improves flow dynamics and evacuation of exhaust gases, which can aid in better engine performance.
• Straight-through core: The perforated core with two-stage acoustic packing maintains exhaust velocity for smoother scavenging and a consistent tone.
• Durable construction: Stainless steel build and satin finish provide corrosion resistance and a clean appearance while being backed by a limited lifetime construction warranty.
• Universal fitment: The 2 in inlet and 2 in outlet and universal design allow flexible placement and orientation for custom exhaust layouts.

Who It's For

The 11224 is aimed at car and truck owners who want a deeper, high-quality exhaust tone and potential performance improvements from a freer-flowing muffler. It suits builders doing custom systems, restorations, or replacements where a universal muffler can be oriented to fit limited space.

Those who should look elsewhere include drivers who need vehicle-specific hangers, flanges, or exact-fit direct replacements from an OE catalog, or buyers seeking a louder, aggressive rasp rather than a deep, resonant rumble.

Pros & Cons
