GT -Transverse exaust

Simply put, the answer is "no".

The transverse dual exhaust system was phased out in the Fall of 1964, way before GT production began. It was replaced with the Arvin dual exhaust system, which was a high performance, low restriction design that featured two "straight through" mufflers and two resonators that were finished off with subtle turn down tips that are just visible beneath the rear valence panel.

Due to many customer complaints about the high noise level of the High Performance "Arvinode" exhaust system, a more conventional muffler/resonator design replaced the Arvinode setup by April of 1965, and was used on the GT Mustangs with the signature trumpet outlets in place of the turn down tips found on non GT cars in 1965-66.

Gene,

As much as we have discussed this the only photos that I have seen on the site are the skeletal remains that CT posted a while back. Does anyone have any decent pics of the Arvinode system? Exterior or undercarriage would be welcome. Maybe Fred Ballard has some stuff he can share.

Interesting that you have one dated as late as 12/65.

Most of the 10-64 dated transverse mufflers are probably leftovers from when they were phased out. The manufacturer must have done one more run after the leftovers were boxed up.

Hope this does not confuse things but thought I would share

I have the differential out of my 12/30/64 San Jose car for undercarriage detailing and was able to take these shots. The car is a non-GT hipo. The car does not have the bolt holes for the GT configuration as it was built prior to 03/65 when the GT exhaust was introduced. The hangers that are shown were on the car when I bought it and appear consistent with Jeff's images. I will be refreshing the hanger rubber during this project. (I think the white stripe on the one hanger is a white wall tire section.) Scott McNair, a former Ford factory manger in San Jose, has told me that San Jose hipos did not all receive the Arvinode system due to distribution shortages at the time. Because of this information and the fact that the hangers were on the car, I chose to put the tranvese system back on the car. The system you see here is a Motive Industries reproduction supplied by NPD. I have run the car with the Motive rear muffler and a NOS Ford rear muffler like the one in Jeff's pictures above. The Ford muffler has a deeper sound and does fit the system, but the one I had was shelf worn and I wanted to prepare for concours driven events so I used the Motive piece. The system required a bit of work in the muffler shop to get it to fit properly, including cutting and rotating the intermediate pipes. When I spoke to Motive about the need to fit the system they told me they had never test fit the system on a car because they had not had access to an original hipo for mock-up. Their rear muffler was right on, but the intermediate mufflers and pipes were several degress off in roation and were up against the emergency brake cables. Cutting and rotating the intermediate pipes by a few degrees solved the clearance issue at the cables. It is a good sounding system.
