Be Loud. Get Noticed
If you're a true performance enthusiast, you just can't help be a little envious when you hear a Thumpr cam by COMP Cams. Nothing turns heads at a car show or a cruise-in than the sound of a hard hitting, high performance idle.
The COMP Cams engineering team called upon 30+ years of design experience to develop the Thumpr series of camshafts. The result of this effort is a series of performance camshafts that deliver the ultimate in modern performance and an incredible exhaust note.
Great Sound. Great Performance.
