Diagnosis Please!

[Coby.]

I've got an '04 182 on around 60k Miles and I recently had the Lower Twisted Engine Mount changed for one of those K-Tec Uprated Jobbies as was getting a Loud Knock when easing off after Hard Acceleration,
Now that has solved the Loud Knocking BUT I now getting a Strange Noise (Kind of Heavy Vibration or Whirring Noise) when I accelerate hard in 1st or 2nd, Its not when I ease off it's during acceleration, it's only in those 2 Gears though :S

Anyone know what it could be and how to fix it?

Thanks
Andy.

Check the exhaust heat shields.
