[E-Type] Heat shield for 2+2 auto

E-Type
1

You have an S1 2+2 auto the same model car as mine.
Does the exhaust in all automatic 2+2 cars go down to a single pipe to go
around the transmission then flare back out into two again.
I found this single pipe was within an inch or so of the transmission and I
was worried that the heat transference might be affecting the gearbox. She
has spent the last few days in a exhaust shop having the exhaust modified
and I’m also getting them to put some heat sheilding round it.
I would have preferred twin pipes is this possible?

I also happen to have a 67 S1 2+2 auto. My car has the bifurcated exhaust
as well, and those pipes do come close to the transmission. I have often
thought about installing some sort of a heat shield in that area, but I am
not sure what kind would be useful. If you what kind of shielding would be
best, please let me know.++++++++++++++++++++++++++++++++++

Mark:

All 2+2, automatic or manual, have siamesed front pipes. Best guess I have
heard is that this was done to prevent resonance. I suspect that the extra
9" works against you when dealing with exhaust systems, by increasing back
pressure. The siamesed pipe may actually perform better than twin pipes. I
used to have a custom bent twin system, but wnet to the siamese system when
a pipe went bad. If there was a difference in performance, I didn’t notice.

Take a look at the twin exhaust system under any of the American muscle
cars of the late '60s and you will find an H pipe joining left and right.
Hot rodders will tell you that this actually boosts available horsepower.
