This 2-1/4 inch dual exhaust system is manufactured right here in the good old USA from an original 1969 M code 351W equipped Cougar. This direct replacement system includes: 1 H pipe, 2 intermediate pipes, 2 mufflers, and a right and left tail pipe. The system is constructed from 2-1/4 inch aluminized piping and features blue printed bends with everything being replicated as close as possible to the original. The mufflers in the system have the hanging tabs attached so that they will accept original muffler hangers. H pipes are constructed for use with original stock cast iron exhaust manifolds and H pipes are also sold separately.
