[DML] Re: Arc Welding An Exhaust System

["content22207" <brobertson@xxxxxxxxxxxx>]

It's JC Whitney's finest stainless flex tubing, 2" ID. 

The system starts with stock manifolds (I told you it wasn't high
performance). The manifolds are attached to the heads with stainless
hardware to facilitate future gasket replacements.

I mated the flex tubing to the manifolds with fittings made from 1 7/8
NPT stainless pipe nipples screwed into "flanges" (actually pipe nuts
-- true flanges won't fit between the manifold studs). These fittings
are secured to the manifolds with stock retainers cut from the old
crossover pipe. The flex tubing slips over the nipples and is secured
with guillotine clamps (stainless of course). 10mm nuts on the
manifold studs are stainless as well.

The flex tubing simply curves around the drive axles and heads towards
the back of the car. By using offset inlet/outlet mufflers, mounted
vertically, I was able to raise the exhaust stream back to stock
height before exiting the fascia. 

As already stated, the mufflers are the only part of the system that
isn't stainless. I couldn't find ready made stainless mufflers small
enough to fit my installation. Considering that they only cost $15
apiece, and can't rust to the stainless flex tubing, future
replacement won't be a big deal.

This whole exhaust setup was inspired by my 2004 clutch replacement.
The car was still K-Jet at that time. When I pulled the crossover pipe
off, I was absolutely stunned by what I saw. Everything that owners
pull their hair out trying to access from above was staring me right
in the face: ignition distributor, heater core takeoff barb and
shutoff valve, slave cylinder, coolant distribution pipe and
thermactor valve, etc. I vowed right then never to put a crossover
pipe on my engine again.

Of course now that I'm carbureted all those goodies are accessible
from above. Oh well, since it's so much less restrictive than OEM, the
dual exhaust is staying.
