Muscle car sound is back and nastier than ever; Thumpr Cams deliver incredible exhaust lope and impressive performance. COMP Cams? designed the Thumpr series of camshafts to deliver the meanest-sounding idle on the block, but we didn?t skimp in the horsepower department in order to make it happen! Even the mildest Thumpr Cam profile produced significant horsepower and torque increases when put to the test. So rest assured that all of the muscle car attitude that your Thumpr-equipped ride will be sporting is going to be backed up by the proven performance that you have come to expect from the horsepower experts.
