Strange noise at 1000 RPM Sign In

Hi guys!

I just replaced the muffler and resonator on my old volvo. The car is much quieter now but there is a strange noise when engine runs around 1000 rpm (at any gear). It is louder inside the car than outside. Here are some videos shooting at different parts of the exhaust system and I cannot notice any significant vibration: Could anyone tell me where else I should look at? Thanks!!

Look for any point where the exhaust system is touching the frame or body without rubber insulation.

Thanks! I will have a look! The car is a 88' 745 volvo (same exhaust used on 740). Both the resonator and muffler are hung under the car with rubber hangers. But I can think of one place that may touch the car frame (the connecting pipe between them).
