Welded Deep-Tone Muffler
The Dynomax ultraflow welded muffler significantly drowns exhaust noise and reduces it to a more pleasant, deep tone. It is made with the strength to last years in the toughest drives.

100% Welded for Extra Strength
The muffler is 100% welded for reinforcement. It is stronger and more resilient compared to stock mufflers and will serve you for years without failing or weakening.

Unrestricted Exhaust Flow
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.

Eliminates Internal Drone
The Dynomax ultraflow welded muffler also features the CRF technology that dampens internal resonance to reduce interior drone and give a deep exterior tone.

Dyno-Proven for Strength
The muffler is dyno tested and proven to perform exceeding expectations, up to an impressive 2000 SCFM.

Tough 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.
