Exhaust noises or vibration resonance, anybody?

Alvon Elrod
My PE #18 has an exhaust noise resonance in the 2800 - 3100 rpm range that is very annoying.  It was noticeable since new, but becoming much more noticeable with more miles (now at 2000).  It diminishes some as the engine warms up, but is there at all times, and in any gear.  It comes from up front, and can be felt in the floorboard.  My guess is that there is something not tightened properly, or parts touching that shouldn't be, or a bad rubber isolator of some sort.

Does anybody else have this issue?

Yes, I have the same at 3k. Not sure what it is or even if it is a fault.

I have the same issue.  I put the car on the lift and giggled the exhaust around, everything felt solid.  Sounds like the heat shields on an old Subaru!  I'd like to get it addressed since it sounds cheap, if anyone figures it out please post here.

My car is in the repair shop now to see if they can figure it out.  I'll keep you posted.
