Description
Overview
The Flowmaster 80 Series Crossflow Muffler is the latest evolution of one of the most popular mufflers in performance exhaust, engineered for builders who want a compact, hard-hitting sound with a clean install footprint. Built with a 2.50 inch inlet and a 2.50 inch outlet located on the same end of the case, this crossflow design routes gases efficiently through a smaller housing, making it a smart choice for custom car exhaust projects where space is tight and side-exit routing is the goal.
Constructed from durable 409S Stainless Steel and finished in high-temperature paint, this Flowmaster muffler is built to stand up to the heat and demands of a real exhaust system. Its compact 4.0 inch by 9.5 inch by 13.0 inch case is designed for easier fitment across a wide range of applications, and the offset (same-end) outlet location makes it ideal for setups where a side exit in front of the rear tires is desired.
Sound & Performance
Tuned to deliver a moderate to aggressive tone, the 80 Series Crossflow gives your ride the deep, assertive note enthusiasts expect from a Flowmaster muffler without sacrificing the flow characteristics that make it a favorite for classic muscle cars. Whether you’re building a complete cat back exhaust system or upgrading an individual component within a larger performance exhaust setup, this muffler brings the signature Flowmaster attitude to the table.
