    Comp Cams is bringing the muscle car sound back, and it is nastier than ever! The lobe profile and grind characteristics of these new Thumpr camshafts use a combination of an early exhaust valve opening, a long exhaust duration and a generous amount of intake and exhaust overlap to maximize the rough-idling characteristics of the camshafts. This gives you a seriously aggressive exhaust note without negatively impacting the power output or streetability of the engine. Thumpr camshafts are available in different grind profiles, each one producing a rough, racy exhaust note while still providing impressive gains in horsepower and torque.
