When I put the 408 in my truck I'm not going to have a cat. I can remebered there being a trick to fooling O2 sensors, but I can't remebered what it was. I'm only looking to fool the post cat sensor.
Anyone understand what I'm talking about?

 

Non-Fouler trick. I think there is a DIY in that section here..

 

Heres a link to HammerZ71 explaining it.

Thanks you guys. Was going nuts last night trying to find that. Couldn't remebered what it was called.
