We recently had some discussion about the correct exhaust clamps to use on your Mustang. Please keep in mind that this post concerns 65-66 GT, High Performance and factory dual exhaust equipped cars with the more common 65-66 Factory GT Exhaust System as pictured above. The reason I mention this is because there were earlier style High Performance Dual Exhaust Systems on the 289 High Performance Mustangs before the GT package was introduced in the early spring of 1965. The clamp pictured above is our part number EH261. This "band" style clamp is used to attach the rear tail pipe/tip to the rear hanger assembly.
The above clamp is a very nice detail for an authentic Mustang restoration. It is the clamp that originally attached the H-Pipe to the intermediate pipe. It, of course, can be used in other areas also. This is our part number EH931. As you can see, this clamp has the nice "FoMoCo" stamping detail along with the unique, original shape and design.
By the way, we have these in 2 1/8 and 2 1/4 inch sizes also.
This last clamp is quite unique. This is the clamp that attaches the GT Exhaust Tip or turn down tip (in the case of a not-GT 289 High Performance Mustang or 66 GT350) to the tail pipe. Our part number on this clamp is EH53.
