Features:

• Reduced noise levels with minimal back pressure
• 5-7 db drop over open collector headers
• Flow 850 cfm

Upgrade your exhaust system with the Moroso Spiral Flow Muffler, engineered to deliver high flow and reduced back-pressure without sacrificing sound quality. Designed for serious performance builds, this muffler harnesses innovative spiral baffling to divide exhaust flow into dual separate paths, yielding excellent airflow while cutting noise levels by approximately 5–7 db compared to open collector setups.

If you’re looking for effective noise control that won’t kill power, this spiral resonator exhaust solution is a smart choice. The core flow capacity reaches around 850 CFM with minimal restriction, making it ideal for high-rpm engines, hot-rod builds, and large-displacement V8 setups.

Crafted from heavy-gauge steel (with stainless steel options available), the design emphasizes durability and race-ready performance. Unlike mufflers packed with fiberglass or steel wool, this model’s spiral baffle system resists flow degradation under intense heat and sustained use.

Installing this spiral flow muffler is straightforward in most performance exhaust systems; simply match the inlet/outlet diameter to your pipe or header system and clamp or weld as required. Benefits include smoother sound character, lower back-pressure, and improved throttle response.

In summary: if you’re building a performance vehicle and need a muffler that keeps power high while offering refined sound control, the Moroso Spiral Flow muffler delivers both function and form. It’s a smart upgrade for any engine bay that demands serious performance with a finished look.
