Metallic vibration
Im wondering if there are welds in the exhaust manifolds, and exhaust pipe, on a 95 with a 3.4? I have a loud metallic vibration sound coming from the exhaust manifold drivers side. Definitely noticeable. Ive checked the heat shield.. This sound resonates through the entire exhaust!! Help!

Metallic vibration sound coming from exhaust
Anyone know if there are welds in the exhaust manifold, and exhaust pipe on a 95 3.4? I have a noticeable metallic vibration noise coming from the exhaust manifold, drivers side. This sound resonates through the entire exhaust. Ive checked the heat shields.. Odd, but seems to happen at 1600 and 2100 RPM..??

The exhaust manifold is chunk of cast iron, so I doubt anyone tried to weld it. If nothing rattles on the outside, then the problem could be on the inside of the system, such as the muffler and cat disintegrating internally.

Sorry guys, probably should have mentioned the car has a new Cat back with a new high flow cat.. The noise is pre-existing. I thought it may have been the old cat before. Well now that the new exhaust is on, the sound is louder.. ugg.
