Title: Early Hipo exhaust question
Post by: Karl @ GT on March 12, 2017, 12:46:50 PM
Hello,    My car is a '65 fastback,  hipo, build date August 1, '64  5F09K250010........We have owned the car since '68. 
When I removed the original exhaust,  it did not have mufflers,   it had two larger resonators where the mufflers are located.
The parts looked similar to the rear resonators but were almost twice as large.

Has anyone here ever seen a hipo exhaust similar to my description?
Thanks, Karl

thanks for your quick reply,    I did see the exhaust on CJs site and that looks very close to the original.   It states from Oct. '64 - March '65.......my car was built  Aug. '64 and had that exhaust from the factory.

regards

It's possible someone liked the sound of the system (I certainly like the sound of mine) and put it on their new car very early in the car's history.

Too early for Arvinode exhaust, should have been a transverse system.

The one with the flat input flanges?

A 65 Gt A code that I acquired for a client has the original crossover section still in use.

The engine has Shelby headers, then 2 down pipes, the original crossover , then two resonators and pipe out the trumpets.

After reading this the resonators might be original, although I can't imagine they survived. 

Would the resonators have part numbers and/or a FoMoCo logo?

The transverse system would have been phased out around October/November of '64.  Wouldn't have been possible to be factory installed on a '65 GT since production for GT cars didn't begin until around March '65.  Also, the transverse system would have been only intended to be installed on K codes, since that was the only car at that time that could have received factory dual exhaust.

Ford serviced the transverse system, so possible it was retrofitted later.

I found my inspection video and here are some exhaust system pictures, I appreciate all of your help to identify original exhaust components.  I will post 4 and continue a few more pics on the next post. Thanks again!

Do you have a picture of the snubber plate under the car?  The rear frame rail pic is missing the upper carriage bolt/nut... or it is obscured in the photo.

Hello,   <<<Too early for Arvinode exhaust, should have been a transverse system.>>>   I have been in contact with the original owner and he states that nothing was done to the exhaust on the car from the time he picked up the car, until we purchased a few years later.   Also, he did not drive the car enough to replace tires, brakes, shocks or any other consumables.   

I can say that the original exhaust on my car did NOT have the rectangle supports on top of the 'mufflers',   the exhaust system was one pc. from H pipe back to the turn downs at the rear valance.   

The car does have the 64 1/2 hood & headlight buckets,  heater switch,  spare tire bolt.   The car is Rangoon Red with red interior.

later, Karl

Hi Charles, ah... what's a snubber plate?

If it's the axle bump it might be one of these, if not, I'll see the car this week and can document anything you like Charles, Thank you!

Keep in mind that 50 years is a long time.  Previous owner's recollections are not always accurate.

If your mufflers do not have the rectangular tops, then those are not Arvinode mufflers.  I think we need to see a pic of what you have.  The only factory dual exhaust used on the assembly line for K codes at the time your car was produced was the transverse setup.

Not sure if you are aware, but your car is most likely a pre-production example.  Meaning, your car may have been built before the re-start of Dearborn for the 1965 model year.  This was the conversion/re-tool time from 64.5 mustangs (generator cars) to regular 65 (alternator cars).  Dearborn re-started the unit numbers with 250001.  Same sort of thing that happened earlier at the beginning of mustang production.  Any of the cars with 05C scheduled build dates were actually pre-production cars and not actually built that day.  09C was the actual first day of assembly plant production.  I have not studied the 64.5 to 65 transition, but 01H scheduled build dates could be used the same as earlier, to designate pre-prod.

If I were you, I'd examine the car very closely looking for anything that appears different or out of place.  It could have been a show car or some special use.  What's the DSO?

Would suggest starting another topic to discuss your car.

So this is what I wake to ...............Look at all this activity !!  (in a month)  Karl@GT  Glad you found this site (or did Nathen) LOL    Lot's of helpful people , much more involved with "specifics" of cars then you will find at other sites/facebook etc etc!  Look at Charles's post above..........he firgured out pretty quick by the number.

MY GUESS IS YOU ARE GETTING BUSY with car!   (Really glad I didn't buy it, would have been sold by now/LOL) I have a trip home next week, will see if I can visit (tried to by a truck in Boyertown/long story). 

Though you know Mustangs, go easy and slow with car.  Too many will give the red azz on "build" if you keep it the way it was delivered.  I would build it the exact way even with the AFB's (too much story with the car to loose) 

Mark
P.S.  Don't let me come there and find a 715 Cathedral Float Holley "just beacuse you had some laying around" !
