i have a chance of buying a used cdc shaker but it came off a 06 anyone know what changed for the 06 to the 07?

and can i just buy the parts or part to make the switch thanks

 

The only major change that I know of is that the '07 hood scoop is held on with holes that are outside of where the Shaker's hole has to be cut into the hood. As long as you do not currently have a factory hood scoop it should not be an issue.
Otherwise the holes that were holding the scoop on will need to be filled first.

 

This is a quote from CDC's web site.
CDC Shaker

2005-8 SHAKER SYSTEM is now available. This Ram Air/Cold Air Package includes all the duct work to make it fully functional. The Shaker System includes an Engine dress up cover, Cast Aluminum Scoop and all the necessary hardware, instructions and templates. In addition CDC has engineered water management systems within the shaker ductwork. The CDC Shaker System uses the factory air box so Engine flashing is not necessary. The CDC Shaker System also comes standard with a High Flow/High Performance S&B Filter. The Shaker System will use your factory hood which has a factory stamping in the hood inner, which accommodates the shaker system installation process, while maintaining the integrity of the hood. We will post updates as they are available. PLEASE NOTE: CDC'S TRIM RING DOES NOT COVER THE FACTORY HOOD SCOOP HOLES (07 FACTORY HOOD SCOOP)

 

I contacted CDC about this issue a couple of weeks ago, and found the only modification necessary is adding a clearance notch in the shroud for the relocated upper radiator hose, so as long as you have a non-scoop hood, you should be ok. Hope this helps.
