Reverberation

[HarleyPilot]

Guys, I have an annoying reverberation through the car on acceleration. It is only in the speed range between 30 and 40 then goes away. I was hoping that it may just be the exhaust touching the body or chassis, but also believe it could be more to do with the actual exhaust.
is this normal? Any ideas or Suggestions would be much appreciated Thanks GG

I had something similar before I changed my clutch. I discovered a lump of cat rattling around. However the position of the exhaust would have moved as well.

Could be manifolds positions ? Often hear of engines mounted slightly off centre.

Does it bang or just vibrate without a noise?

[HarleyPilot]

No bang more like a resonance at low rev and speed

I had this on mine when I first got it between 7000 and 7500rpm.
It turned out to be my sphincter would you believe.

Hehehe! A tad over my 3 to 4000 then

Sure it wasn't the rev limiter beeping furiously?
