The Rocket Cams product line offers all components to round off performance motor builds and to " make the Big Bore sing ". When more of a ' Cruise ' ride is desired , the best Rocket Cam profile to select would be the 464 or 474 , while the 544 works best for a ' Hi-Output ' application . The Twin Cam 110 " kits pair perfectly with the 574 cam profile for a ' Cruise ' scenario and the 584 cam for the ' Hi-Output '. Rocket Cams provides its dealers products made from the world ' s top industry leaders in V-twin performance manufacturing , from cams , performance clutch kits , valve spring kits , hydraulic lifters , Speedy pushrods and Hi-Flo performance air intakes . " Cruise modifications are for the heavier / 2-up riding or customers that require more power and torque in the lower rpm range , and the exhaust option can be as simple as a good hi-flowing muffler added to the stock head pipe ." Hi-Output modifications are for those riders that want to be more aggressive throughout the rpm range . " This level requires a free flowing aftermarket exhaust and works even better with the addition of a larger intake manifold and / or throttle body . Ported
