Having dual exhaust Magna flows put in my 1971 Mustang Mach1 which now has single exhaust. 351 4bbl small block Windsor.
Question is do I need a X or H pipe? The muffler man who has a lot of experience told me he doesn't feel I need it. His reasoning is it is not a daily driver, not towing and not being run at high Rpms.
What are everyone's thoughts?
