I have an A code mustang fastback with dealer installed GT package.

What appears to be factory installed, Quick ration steering, front disc brake, 4-speed top-loarder trans and pony interior ( 5 bezel instrument group from factory.) Build date Feb 18, 1965.

The dual exhaust set up does not look factory, but notice the welded and threaded frame rail bolt/support for the exhaust.

Question: Would a a code car come without dual exhaust and what about the threaded bold inside the frame rail?

Thanks!

Dual exhaust dual bracket off frame rail

Those threads are for tie-down plates found on all Mustangs.

That doesn't look like dealer installed, more like Humphery and Buck installed.

definitely not a factory dual exhaust.

You can buy correct dual exhaust mounting brackets online so you can remove those incredibly long bolts. Not only is that setup rigged those bolt could stab a passenger in the backseat if you hit a large bump in the road.

At the very least, take a pair of bolt cutters and lop them off to a more acceptable length then tidy them up with a rasp.

Thanks, guys! I thought all A codes were dual exhaust cars - guess not.

Factory GT's only. You may want to put some extra re-inforcement metal on the inside of those screws so you don't bend/warp the unibody.

nope, strangely enough, a dual exhaust non gt 65 - 66 car is virtually unheard of for some odd reason that seems to defy logic . . "lets build a more powerful engine and put sh_tty single exhaust on it" . . what an incredibly brilliant idea.

The T-code, C-code, A-codes (non-GT) were designed to run very quiet,which included the use of the single exhaust. Its one of the reasons why they used the large plastic timing gear sprocket!

I heard a stock 55k original mile C-code running once and you could barely tell it was running.

Thanks again! So it must have been very common for A-code, non factory gt car owners to add the dual exhaust.
