I would have liked =
to use
stainless, but had problems finding any in 1". So I used copper, and=
the
guy who posted this idea on one of the f-body boards also used copper. &n=
bsp;
I think he used a straight piece of 3/4" while I used two 1" 45s
for 1" copper tubing. I liked the 45s because you can turn them and =
also
adjust your distance. You can get these at any hardware store in the plum=
bing
section. One end of the 45 is flared to fit over 1" tubing, or in th=
is
case the other 45. (These are 45 degree street elbows for copper tubing.)=
The
pipe is installed between the inlet to your muffler and the right tail pi=
pe
out of the muffler. Sort of a poor man's Borla with a 1" plate. I put
the two 45s together loosely, and marked the pipes about 31/2" to
4" out from the muffler. For 1" tubing I used an 11/8" hole
saw in an electric drill. This was the hardest part. Getting the dr=
ill
under the car as I did not jack it up or anything to make it easy on myse=
lf.
The first picture shows the holes after I cleaned the edges up some. The
second picture shows the cross over in place. You can see that I put a pi=
ece
of wire to hold it while I finished the job. Since I do not have the
equipment to weld or braze metal I used a two part epoxy. This is one of
those sticks that you mix together until it is an
uniform color. I then formed it in. Only mix enough for one side at a time
because it sets up real fast. After 20 minutes or so I removed the
wire, and positioned the other end for a good fit. ( don't let the 45s st=
ick
into the exhaust pipes) I have had good luck with this epoxy in the past,=
but
I have questions about how it will hold up to the heat. I measured
280-290 degrees F at the weld. Anyway, I have had no problems with this, =
but
I am going to keep an eye on it. It would probably be better to braze it =
in
place. Time will tell. The third picture shows the finished job, and the =
fourth
picture to shows how the copper is turning color from the heat, and start=
ing
to look like the rest of the pipes. This is an easy mod if you deci=
de
to do it. The 45s cost me $2.44 each, and I had the epoxy in the garage.
Note: I did not put any epoxy between the 45s. No leaks, but I am watching
it.
Editor's Note: You may want to have th=
ese
pieces welded in place to prevent them from falling off in case of epoxy
failure. For a short term solution, a strong expoxy should hold fine
for a few weeks, just keep and eye on the joints.
