Cat delete? - Toyota Yaris Forums

yariSB86 · 06-16-2012, 10:28 AM

when either removing the cat converter or having an aftermarket mid pipe that does not have a cat, what kind of tuning do i need to tell the ecu o2 sensor to not freak out? and what kind of shop should be able to do this?

Using our midpipe (either Nitto or the incoming Megan Racing), no tuning was necessary. An O2 anti-fouler kit keeps away the CELs.

And the Yaris has TWO cats, just FYI.

yep goes like this from the head:

header (with sensor) > midpiping > cat > sensor > cat > resonator > axle-back exhaust (muffler and tip)

Dang they want our cars to be quiet and the pipes to be restrictive. Wonder has anyone on here replaced/removed one of the cats any or the resonator

Have to love places like here in Michigan. No inspections and no emissions :D

Can't even tell you some of the rediculous things I've seen on the streets that in no way could pull it off
in other states with inspections/emissions.
