Hi guys.
Sometime back I asked the list if anyone had discovered a stainless
exhaust system that fit with a minimum of problems. The consensus was
that Falcon Systems appeared to have their quality control issues
straightened out. So I ordered a system From a Moss distributor.
Here's what I found, starting at the front:
Picture #1,4,5
The forward pipe from the manifold to the muffler has the flange
welded on crooked, swinging the pipe inward. It jams against the rear
pipe and won't allow the flange to lay flat against the manifold. I
only found this out after having to file the flange holes to get it on
the manifold.
Remedy: Heat pipe just below the flange and pull it out bit by bit.
Picture. There is a picture on page A03 Moss Fall/Winter 2007 Moss
needs some engineering help. Their drawing doesn't correct a damn thing.
The Flange itself is the most bazaar piece of crap in this whole set-
up. It is obviously laser-cut, holes and all.
The center to center distance between the flange holes is 2.365. The
center to center distance on the exhaust manifold studs is 2.493.
That makes the Falcon holes 1/8" too close together.
So what did the brilliant engineers at Falcon do? They made the holes
bigger. (.470) But not quite big enough, as I had to file about .030
on each hole to allow the flange to go over the manifold studs which
are .312 Dia.
Precision Engineering.
Picture #6
The front pipe is about 1" too long at rear of the flex area. This
means the part that slips on the muffler will have to be cut off.
The front bracket on the muffler is in the right place, although it
could be 1/2" shorter.
Picture #2,3,8,9,10
The Falcon hanger at the rear of the muffler/front of the tail pipes
is off-center with a bolt welded in. My old pipes had the bracket
hole centered between the pipes, I can't move the pipes over as the
muffler hits the rocker and the pipes won't lay in the relief in the
outrigger.
Remedy: Saw off Falcon bracket. Make up a bracket to clamp both pipes
with a stud on center.
Picture #7
The angle clip at the extreme rear is welded on to the tail pipes
about 1/2" too far forward.
Remedy: Make two 1/2" spacers to put behind the mounting bracket.
I have pictures of all of this which I'll be glad to provide for
somebody to post.
Dave and a thoroughly exhausted Daisy
