True Dual Performance

Flowmaster's 80 Series Cross-Flow Mufflers offer true dual performance where only a single exhaust system will fit, commonly found on classic Camaros and Firebirds. The 80 Series Cross-Flow Muffler fits transversely behind the rear axle and in front of the fuel tank making it the perfect OE replacement. The 80 Series gives excellent ground clearance, aggressive tone and increased power output over stock.
