Gets the job done.

Great Product from a Great Company

Extremely well made j-style defouler. Fitment was perfect. For my Focus ST I used the middle size restrictor on my catless downpipe. I'm also running a big turbo. Not a single CEL since installing the defouler.

J angle defouler

Very good craftsman ship. Only request would be to include recommended sizing for restrictors.

Perfect fit.

Perfect fit. Worked as expected.

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.
