80 Series Cross-Flow Mufflers
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.
