I have a 1972 MACH 1 with 351 Cleveland. I have installed a Cherry Bomb exhaust which it to loud. I am planning to replace it with a Flow Master Exhaust which has the deep sound of a mustang but not too loud. Does anyone have any recommendations?

Do you have the turn down ends on the tail pipes or are they straight out?
You replacing just the mufflers?

I have always liked the sound of an H pipe and original 40 series flow master mufflers. Especially when they are behind a set of long tube headers. Put that combo on a Cleveland, that’s music to my ears.

With a 351C and if you have headers (please tell me you do) then IMO you would want 2-1/2" at a minimum (3" will be better) exhaust with either an H or X pipe, your choice of mufflers, and tail pipes out the back.

I heard a set of Flowmaster Super HP-2's last weekend on a 347W with 1-3./4" full length headers and full 2-1/2" exhaust with an X pipe and it was super nice. I am considering swapping out my 40 series on my Coupe over to them.
