Full throttle acceleration in our 1972 Trans Am with new crossflow muffler from Waldron Exhaust.
The transverse-mount muffler uses tubing that's traditionally routed and is designed for improved airflow over an original. The numbers-matching 455 HO engine features a Nunzi hydraulic flat-tappet (222/232@ 0.050-inch duration) camshaft, but is otherwise stock.
