    All Dynomax Systems are true bolt-ons designed to attach directly to existing mounting points for easy installation. They follow OE routing with top-of-the-line performance mufflers, mandrel-bent pipes for smooth exhaust flow, and all-aluminized materials for good looks and longevity.

    Dynomax SS Exhaust Systems are made completely from stainless steel. Each kit is dyno proven to make more horsepower & torque. Free-flowing Ultra Flo Welded Mufflers and mandrel-bent tubing increase performance & fuel efficiency.

    Dynomax Super Turbo systems feature Dynomax's flow director technology with large internal flow tubes that eliminate turbulence and improve exhaust flow while reducing backpressure. The fiberglass matting gives the Super Turbo a mellow performance tone.

    Dynomax Ultra Flo Welded systems feature a stainless 100% welded muffler that uses straight-through design that ensures unrestricted airflow and reduces backpressure. These systems have a deep performance tone.

    Dynomax Ultra Flo systems feature a seamed, unwelded, 100% polished stainless muffler that uses same straight-through design of the Ultro Flo Welded systems. These systems have a deep performance tone and will support up to 1,900 horsepower.

    Dynomax Race Bullet systems feature a lightweight, compact, race-oriented muffler that provides up to a 4 dba sound reduction on most race applications. These systems are designed for vehicles with limited space and produce a deep race tone.
