Hey folks,

I'd like to put a header exhaust system on my air cooled bus, but keep
the heater boxes.  Does anyone make a system that bolts on after the
heater boxes?  Is this something I would need a  custom exhaust guy to
do, or does someone make a bolt on?  I've searched around on the net,
but all I can seem to find is systems for water cooled vans.  I would
expect to lose the cat using a set up like this, but would like to keeep
the O2 sensor.  Could I just drill a hole somewhere in the header system
and fix the sensor in place?

Thanks folks..

Greg.
