This may be the perfect solution for running a catless exhaust without having to code out your readiness codes. It's a secondary lambda extender with an HJS mini catalyst cartridge. Has anyone tried these? The are only about $65 each.

edit, reviewed it...neat product!
wonder how well the catalyst works though, although in a hot zone, not necessarily heating up to true 'hot' standards as there's no real flow through, guess it doesn't require much as even standard spacers do a pretty good job...hope that made sense...

 

The small Euro 4 catalyst cartridge acts as a scrubber. That combined with that extender will keep the CEL from tripping without having to do any ECU programming. At least that's how I see it. FVD sells these also.

 

ya exactly, just wondering how effective they are...either way would be an improvement to standard spacers.


Would be neat to see if someone with their catalyst monitor still active could try them with a de-catted exhaust....

 

Yes I had them, they didn't work and threw codes P0132 and p0152 couldn't figure out why since I had them installed on the secondaries, car ran sluggish and supper rich.
I removed them and installed the 90 degree O2 extenders and codes went away and car felt more responsive.
Car ran super rich with them, they might work on other applications but did not help me.

 

I have never used or known anyone that has but I seriously doubt they would work= too small.
