Shelby Cobra Exhaust tip
By Dave Beswitherick
Ok, so it was time to do up the exhausts, and the Cobra has a very distinct header array that really
completes the cars overall shape and style.
This is what came with the kit:
NASTY! this is just not an option for me so, I read a tutorial in a magazine a while back on how to
make custom exhaust pipes for the Cobra. I’m not going to do it exactly the same way as it involves
materials I can’t seem to find, and it also involved soldering which I’m not really set up for.
This is my version of this method, and here’s a shot of the materials chosen.
-14 gauge copper wire(12g. would be better)
- 4.75mm aluminum tube
- 3.75mm aluminum tube
- 3 mm solder
- Thick consistancy CA glue
First, I cut the wire into 4x 4” lengths
Then taped them together nice and tight because I’m going to bend them 90 degrees.
Then I let the CA’s capillery action soak into the wires.
Outer tube cut 1” and cleaned up, all the measurements were taken from the kits pipes.
Next I will have to bend the inner pipe, I use these bending coils from K&S they work great.
Pipes are now all cut and cleaned up time to assemble:
I just used CA to assemble everything.
I drilled some locating pins (brass rod) so I can mount the unit.
And that’s really all there is to it, I finished off the copper parts by polishing the copper and
spraying with Alclad II Chrome. The aluminum is polishable.
I then hit it with some Citidel sepia from the airbrush to simulate heat crazing and this is the
Each pipe took about 20 minutes to create and achieved a fairly good representation
of this exhaust system when compared to the kit option.
And no blow torch and hot solder nonsense
