Catted O2 spacer recommendations

[Mahu24]

Did these work right away?

Never had a code with these

Hello all,

I’m going to have to go in for emissions soon and my o2 sensors are throwing P0430/20 codes due to my stainless works downpipes w/ Gearhead AO tune. I got a recommendation from someone trusted in the community for these catted o2 sensor spacers (as well as recommendation that the spacers would in fact set the I/M monitor to ready): https://www.racdyn-usa.com/PROD/130+10+10+013.html

Before I drop the money on them I just wanted to see if anybody else had luck with this strategy, and to confirm whether or not I should go with straight or 90 degree ones. Also i should add I’m not keeping these on forever, just putting them on to pass emissions and then removing them later on

Just passed emission 2 months ago with them.
