Description
The Flowmaster 80 Series Crossflow Chambered Muffler is designed for transverse-mounted exhaust systems where the muffler is positioned behind the rear axle. Featuring a true crossflow layout with dual inlets and dual outlets on each end, this muffler is an ideal replacement for vehicles such as Camaros and Firebirds equipped with factory-style transverse mufflers.
Built around Flowmaster’s original two-chamber design, the 80 Series delivers an aggressive muscle car exhaust tone both inside and outside the vehicle, with noticeable interior resonance that performance enthusiasts expect. Constructed from durable 16-gauge aluminized steel and fully MIG welded, this muffler is engineered for long-lasting strength and consistent performance.
