Dynomax – Thrush Turbo Muffler

Description

The Dynomax Thrush Turbo Muffler (part no. 17703) is a universal performance muffler built in the storied Thrush tradition — a cornerstone of hot rod culture for over 40 years. Constructed from 100% aluminized steel for maximum durability and corrosion resistance, this compact oval-body muffler (3.25 in. H × 7.75 in. W × 11 in. L) features a 2.0 in. single offset center inlet and a 2.0 in. single offset outlet, delivering consistent exhaust flow with that classic Thrush performance tone. The revisable design with time-proven spun-locked heads ensures a leak-free seal for long-term reliability. At 16 in. overall length, this muffler fits easily in tight undercarriage spaces. Compared to the 17702, the 17703 features an offset outlet instead of a center outlet, providing greater installation flexibility for various vehicle configurations. Proudly manufactured in the USA.
