Does it have a catalytic converter? - AB
This will likely be the deciding factor on whether it's STR legal or not:
E. Catalytic converters: Any catalytic converters are allowed, but must attach
within 6” (152.4 mm) of the original unit. Multiple catalytic converters
may be replaced by a single unit. The inlet of the single replacement converter
may be located no further downstream than 6” (152.4 mm) along
the piping flow path from the original exit of the final OE converter. The
extents of an OE converter are defined by the expansion chamber in which
the catalyst is contained, regardless of placement within larger exhaust
sections. Replacement converters must have a minimum catalyst density
of 100 cells per inch and minimum substrate length of 3” (76.2 mm).
