A nice big box showed up today!
My new Ford a Racing, M-5200 - F15R145L, . Made for the 145 inch wheelbase super crew , and is the new system with NO RESONATOR, welded on chrome tips , and the twin muffler setup that tucks up nice and tight. The "L" at the end specifies the "Sport " system where a "C" would be for the touring. As far as the difference , I think the only difference is the resonator included with the touring kit.
There is a long pipe in the kit that replaces the stock pipe with resonator.
SCAB owners would order the 133 L or C , for 133 inch wheelbase.
Putting it on in a few days!
I'll post when I can
