This direct replacement is the 2-1/4 inch H pipe only and is for any 1970 Mercury Cougar or Ford Mustang with stock cast iron exhaust manifolds without the passenger side spacer. These units are manufactured right here in the good old USA from 2-1/4 inch aluminized pipes and made from an original 1970 Cougar and Mustang with the 428CJ engine. We also sell this H pipe in a 2-1/2 inch diameter and have OEM style dual exhaust systems that include the H pipe, mufflers, and tail pipes.
