w126 420 sel Dual Exhaust

[macdoe]

Where do you get your true dual exhaust? I have found a euro 560sel and it has only 86,000kms according to the owner. It has been hit lightly in the front pass side. and he says it sounds like the cats are plugged when it is running, although I never heard it.

From his description of metal to metal sounds by the engine while running, I am thinking it is not the exhaust...cause that just does'nt make sense. More likely...something is rubbing on the accesory pulley's due to the front end damage. I am wondering if the exhaust headers and related dual exhaust setup being that this is the euro model would work if it was removed from the 560 and bolted onto the 420 sel north American version? Thanks
