Comp Cams Mutha' Thumpr NSR camshafts make power from 1,900-7,300 RPM. They are a direct fit for 2015-2017 5.0L Coyote powered Mustang GT's. The Mutha' Thumpr NSR camshafts feature a grind profile that does not require new springs, keepers or retainers. 

Comps' Mutha Thumpr cams have significantly more exhaust duration that equates to a lopey choppy idle with power gains in the higher RPM ranges. Unique to the 2015-2017 Coyote mid-lock phaser sytem motors, these cams have a more aggressive profile than previous versions and do not require neither phaser lock outs nor limiters

Got these comp cams mutha thumpers a year and a half ago, and couldn't be happier, no they don't have much of a bumpy idle the stock unlocked phasers cancel it out, but driving or accelerating you can absolutely hear them, non of the other coyotes in the are sound like mine especially with the current outlaw mufflers, but with the brand new Gen 5 3.0L Whipple supercharger it too loud, thinking of switching to the Flowmaster flowFX mufflers for a deeper basser exhaust sound vs raspy racing screaming banshee that I have now, with the cams and headers went from baseline 379hp and 342tq to 452hp and 440tq at the wheels, great mid to high end power gains
