Lethal Performance upgrades its GT350 project with Kooks exhaust

By Steve Turner

Pushing the performance of its project cars is Lethal Performance’s calling card. Soon after leaving Weikert Ford in a cloud of smoke, Team Lethal embarked on an aggressive modding plan for its Shelby GT350 project car, including bolt-on upgrades, a 10-second run at the drag strip and, eventually, a Whipple supercharger.

When we last left the Lethal Performance Shelby GT350 the car had received a 2.9-liter blower from Whipple Superchargers and developed over 819 horsepower and 605 lb-ft of torque. That was through the stock manifolds, a Lethal Performance mid-pipe and the stock cat-back system.

When you start pushing that much air through a high-winding engine like the Voodoo 5.2-liter engine, maximizing the airflow is crucial. Lethal started out by opening up the exhaust with a cat-back exhaust, but the time had come to open it all the way up by replacing the factory manifolds with full-fledged long-tube headers and a supporting exhaust from Kooks Headers and Exhaust.
