Hi,

My '85 Vanagon is acting very sluggish.  I have also noticed that the engine
sounds more like a motorcycle engine then a vanagon engine.  I am wondering
if I have a block in the exhaust system.  It looks as if the muffler and
catalytic converter has not been replaced since new.  So how can I test if
my problem might be exhaust related?

Thanks,
