FLOWMASTER 80 SERIES CROSS-FLOW MUFFLERS

For True Dual exhaust performance where only a single exhaust system will fit such as is commonly found in classic Camaros and Firebirds, the 80 Series Cross-Flow Muffler fits transversely behind the rear axle and in front of the fuel tank, the OE placement. With single or dual inlets, the 80 Series gives excellent ground clearance, aggressive tone and dual outlets to fit muscle cars requiring this specialized fitment. Constructed of 16-gauge aluminized steel and fully MIG-welded for maximum durability.

  • Aggressive sound and increased power/torque output over stock
  • Perfect replacement for Camaro/Firebird configuration
  • Available in stainless steel or aluminized steel
  • 409S Stainless Steel muffler backed by lifetime warranty
  • Available with either single or dual outlets
