Dual Exhaust Cutout Valance
#1
Hello Fellow Enthusiasts; How was it determined if a dual exhaust 71-73 Mach 1 was equipped from the factory with the dual exhaust cutout rear valance. I have a 73 Mach 1 CJ VERY original, has factory dual exhaust yet has NO cutouts!...Please tell myself/others if your 71-73 Mach 1 has the dual exhaust cutouts.....VERY interested in how this "option" (?) was determined....Thanks for your input/s!!...Mark

My 73 was built in November of 72 and has duel cutouts.

Your car should not have the cutouts
Most 73's did not get them

from what I have seen and heard, they came with the exhaust turn downs.

but I personally like the cutouts.

As the original owner of "Fire" (my '73 Mach 1), I can definitively state that my Mustang did not come with the cut outs...but I do like them and will probably install a different rear valance when I do the next paint job.

I recently had the exact same question and my research led me to the following fact from a Ford book somewhere...

Cars after 1/1/73 were installed with turn downs do to changes in emission/noise level laws. Cars before this date would have normally had the tips.

I bought a NOS valance with the cutouts to swap out on my car. i like the look also and read a few posts that some aftermarket valances were manufactured too narrow and require a lot of work to make them look normal. I always find it interesting that the 71 BOSS 351 had dual downturned exhaust without the cutouts. But the BOSS exhaust system also had the tail pipe sections welded to the mufflers for some reason.

You are probably "on to something" there Jeff as my '73 was built in February 1973.
