[DML] Dual Exhaust -- Clarified

["content22207" <brobertson@xxxxxxxxxxxx>]

Is clear from off List messages that I neglected to adequately explain
my custom dual exhaust:

Am using stock manifolds and studs. I am also using stock crossover
pipe gaskets. Mated to them are custom flanges made from stainless
pipe nipples (threaded one end) and pipe nuts. Pipe nuts provide the
manifold mating surface and the pipe nipples hold my flex tubing.
Flanges are held to the manifolds with stock crossover pipe retainers,
cut off my old crossover pipe. Used stainless nuts on the manifold
studs and stainless guillotine clamps throughout.

Stainless flex tubing loops around the drive axles, to the outside of
the engine cradle, then passes between the lower support arms and axles.

Mufflers hang vertically in the dead space under the rear frame
extensions (between the engine cradle and the rear fascia). Are offset
inlet/outlet. Exhaust enters offset closest to the pavement, and exits
offset closest to the frame. From there it's about 8 inches through
the stock fascia tailpipe cutouts to the back bumper.

I used generic muffler hangers, bent to match my mating surfaces and
excess holes cut off (used 2 holes per hanger with stainless lag
screws). Lower offsets are attached to the outside of the engine
cradle. Upper offsets are attached to the underside of the frame
extensions. To reduce height,  upper hangers, were rotated into a Z
shape (rubber angles towards outside of the car, clamp retainers angle
towards inside of the car). Hangers actually grip the side of the
muffler outlets, not the top. I drilled & pinned the hanger washers,
through the rubber, with cut off finishing nails to hold that sharp Z
bend.

Note that the passenger pontoon extension had to be cut to match
driver's side. One of these days, time permitting, I may patch it with
fiberglass. Can't really see it behind the muffler however.

I will post pics to #5939's photo album AFTER car is reaseembled.
