Overview
COMP Cams is cranking up the muscle car attitude with the Thumpr camshafts—bringing back that mean, thumping idle. Nothing turns heads at a car show like a rough, high-performance exhaust note, and Thumpr cams deliver just that.
Engineered with a unique lobe profile and grind, they maximize exhaust overlap for an aggressive sound without sacrificing power or drivability. Available in multiple profiles, each Thumpr cam creates a distinct, race-ready exhaust tone while delivering strong horsepower and torque across different RPM ranges
