1972 Trans Am full-throttle acceleration with new crossflow muffler

Our 1972 Trans Am with new crossflow muffler from Waldron Exhaust accelerating from low speed.

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.

70'-73' Trans Ams were the best looking muscle cars of that era. I love that car! Take good care of her!
