Message My '91 TT has a strange noise coming from the right rear. It only happens at low RPM (any gear and especially if the engine is lugged). It sounds like metal rattling and it goes away once the RPMs are up (around 2000). I've checked every shield possible and still get the noise. Then I noticed that a weight was missing from my one piece drive shaft and had it balanced and the u-joints replaced. Still getting the noise. My mechanic is seriously puzzled. We think it could be the right muffler (it's an HKS cat-bak system). My mechanic thinks it could also be the HICAS system. Any thoughts would be greatly appreciated.
