2000 ls 400 exhaust leak and engine vibration
My 2000 ls 400 has developed an exhaust leak. It sounds like it could be the manifold gasket. Not that loud but it sounds like air being squeezed out of the gasket. Any ideas on a price to fix?
Also, the engine vibrates when pressing the gas in neutral or while accelerating. I am thinking it is one of the engine mounts. It is not smooth like this engine should be. Any help would be great.

you can try using window weld for the motor mounts itll keep them solid. My friend did that to his car,and no enigine vibration.
Did you check all the exhaust flanges and bolts to see if any are loose??

No EGR on the 98-00 models so that is not it. Not likely the manifold to head gasket. Probably the manifold to cat or cat to downpipe OR some damage. Hard to say on the vib as 98-00s do that (mild) under some conditions.
