Catless Mid pipe o2 anti fouler success rate?

[fourbangingfun]

What's up everybody. I just had a quick question to those of you who are running micro image's o2 anti fouler.

I'm considering cutting out my front and rear cats and replacing with glasspacks of some type. I just wanted to get an idea of how well the o2 spacers worked for you guys on your yaris'.

I already ordered the anti fouler from Garm, but just wanted some extra reassurance before I have my local exhaust shop actually cut out my cats.

P.s. I have an 07 sedan so there is no catless bolt on mid pipe that I know of unfortunately.

Unless this is a dedicated race car, cutting out the Cats is absolutely useless as they do not restrict the exhaust.

Yeah, it's definitely not a race car. I was just going to do it mostly for sh*ts and giggles and a possible slight increase in mpg. I like the smell of unburned fuel ;). I realize some folks on here are probably at odds with that mindset. I respect that point of view, I just have a different outlook of life I suppose.

I'd just have a custom mid pipe made then. That section is probably close to $1000 from toyota.

Yeah I would go the custom route for sure. I was more so wondering about the effectiveness of the anti fouler with keeping the CEL off.

I've never had one returned because it didn't work, if that helps. :)
