1972 Dart Swinger exhaust over axle options

You probably can,you will also need a muffler with the correct offset and lenght for it to work IF the front exhaust pipe is correct to fit with that tailpipe. Alot of people miss the part that not all exhausts are created equaly,sometimes different brand tubing will fit togheter and sometimes not even the same brand will fit with itself,due to changed angles during updates.
I worked with exhuastsystems for 10 or so years and never saw the end of it.
