No more Check Engine Light!

I installed the Whoosh J-style defouler because I was running a Catless downpipe and it was throwing a P0420 code, on my Focus ST. I switched to a Whoosh Catted downpipe, and installed this defouler with the middle sized insert, and I no longer have any codes or a check engine light. It worked perfectly.

Did the trick

Easy enough install despite the tight spot, and got rid of the PO420 code for good using the medium size orifice.
