Re: Resonating Sound w/RPM; Possible Exhaust?
As long as you're POSTIVE the noise is not coming from the motor or tranny then definately suspect the CAT. Don't know of any way to check it. I do know that muffler shops can check them, but don't know how they do it. Could also be the muffler itself???
Another sign of a restricted exhaust is a rise in engine temp under a load. Have you noticed that???
