Ultra-Flo Deep-Tone Muffler

The Dynomax ultraflow muffler significantly drowns exhaust noise and reduces it to a more pleasant, deep tone. It is polished for a classic shine and is made with the strength to last years in the toughest drives.

Improved Horsepower

The straight-through design allows an unrestricted flow of exhaust gases. This reduces turbulence and optimizes engine capacity for increased horsepower and a generally impressive performance.

Reduced Internal Resonance and Drone

The muffler also features the CRF technology that dampens internal resonance to reduce interior drone and give a deep exterior tone.

Dyno-Proven to Perform

The Dynomax ultraflow muffler is dyno tested and proven to perform exceeding expectations, up to an impressive 1900 horsepower and 2000 SCFM.

Stainless Steel Construction

The muffler is made with tough and exceedingly strong stainless steel. It is resistant to rust and corrosion and is durable to serve you for years beyond expectations.
