The inliners have
the most spectacular exhaust sound of dual splitted pipes. The RAP! you
got is far off from the humming sewing machine originally.To achieve
this split manifold, or double headers are the only way.
Since one of my targets is doing the work by my self, i
also stepped on to do this. A lot of guys says to beware of welding the
cast manifolds,
but lot of, has done it successfully in the garage with use of a torch
and
MIG welder.
Its shore gonna be some work, with not any insurance thats gonna
hold
over time, AND, need of difficult pipe routing, to not destroying it on
roaduse. ( low ground clearance) planned connected to both sidemounted
lakepipes. . ... .
The exhaust manifold was splitted direct after the outlet position,
creating 2 halves with one double, one single outlet, to both. (
3cyl each ) |
Cuttet
as
near aft of the outlet as possible,to keep the carburator heating
intact.
Plates of 2,5mm was maked for closing the ends.
All edges was grinded with angle to get most possible good welds.
Manifolds
was heated to nearby red glow, before MIG
welding, with mid/high setting, letting it get chance to really "burn
trough."
Hammer
knocked the welds to get most of the stress out of materials, let it
cool and inspected for cracks, or holes. |
 |
I
cut
approx. 3cm more in front of the rear part, to fix placing for the
welds.
An outlet was cutted of another manifold and mounted near front
of the
rear part. This to get as much place around as possible for mpunt of
the pipes.
Grinding was only done where more welding was needed.
When finished, recheked for cracks, all welding was soaked with
penetrating oil, against corrosion. |
 |
Complet manifold welded and ready to mount.
Rear outlet is angeled little inside to route the pipe without
interfear with the front pipe..
Pipes are located to remove the stress on outlets
by connected to a lower mount on the engine.

Rear exhaust manifold on place, with new gaskets
made
of a stored sheet of "Klingerit". This stuff is not in use any
more because of the asbests in it, but was videly used as gasket
material in the past. It did stop all leaks perfectly, and withstand
heat, gas, or oil perfectly. |
 |
Complete manifolds mounted.
Front 3 cyl uses the original outlet/ pipe, rear 3 cyl have the new
outlet behind.
The flange here is cutted from a Chevy 6.2 D, who did suit very well. |
 |
Of
course, i could sandblast & maked a little shine before reworked,
but wanted to see the posibillity of using the MIG weld at first.
When seeing the result, i did sandblast it, and som finishgrinding is
done at the welds, for a better view.
Also
get later a tip that Mercedes Benz exhaust manifolds have
tendency to get broken, and normal procedure on garages is to weld,
mostly by use of heating by running temperature and use the MIG.....
