Don't know about the CVEC pipe and the Savage. Only experiance I have with Cvec is with a tmaxx. Produced more power but was a little trickyer to tune. My Suggestion is to try a THS racing pipe for the savage .25-.28. Part number is THS8025. Please note that THS has a pipe for the 1/8 savage and the .25-.28 savage you want the one for the .25-.25. If you get the one that just says 1/8 savage you are getting the one for the .21 savage. I have found that the THS pipes work the best. good luck
