Your catch can or can system on the same order as this item will now arrive with an XL can assembly and the required mating mounting clamp.  The standard extra port on the XL will automatically get a hex plug fitting.  This does not increase the power handling of the current kit, but does increase its storage capacity and is easily upgraded beyond the 1200hp cap of the standard size cap for future increases.


This does not work for WILD fitting top OR short body conversions! 


If you add this to a RACE can it will continue to be fully open, and if you add this to DRAFT / PCV can it will continue to be vacuum closing.
