For 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. This makes our Flowmaster 80 Series Cross-Flow muffler the perfect OE replacement - but with enhanced performance and sound. With single or dual inlets, the Flowmaster 80 Series Cross-Flow gives excellent ground clearance, aggressive tone, and offers dual outlets to fit muscle cars requiring this specialized fitment.

Perfect replacement for Chevy Camaro / Pontiac Firebird
Available in aluminized steel or 409S stainless steel
409S Stainless Steel muffler backed by a lifetime warranty
Available with either single or dual inlets
