Hi,

I cant imagine this not being covered as im pretty sure ive seen people talking about it before.

I've tried searching for my answer but seem to get flooded with hundreds of results to do with decat's but not solving the issue I have, so I hope someone could possibly help with a link or reply!

I have a HKS exhuast with spoon decat. The engine management lights been on for a while now and I need to get this fixed.

Is there any way for me to trick the emission sensors so my light will go off.

Any help would be great to solve this issue without changing my decat pipe.

Many thanks

 

Do a search for anti-foulers.

They move the O2 sensor out of the flow of gasses.

 

I might have some left, one of the pair will need drilling out to 1/2 inch though as I don't think they are drilled.
