Hey guys, I've been searching threads and vendor sites and can't seem to find anyone that makes 02 foulers (to keep the cel from coming on) to run cat delete's. Thanks for the help.

 

any universal j tube should do what you want

 

Hey Ern,
These worked perfectly on my Audi. No cats for 2 years without any issue. Breezed though emissions too.

i had those mini cat things ( bung extenders? dont know what they are actually called ) and took em off.

when i got 02 below limit cels i replaced the sensors with new ones and haven't had any cels since cat delete.

 

These were what I was thinking of using

They don't work on stock Ecu.
When I put in my catless exhaust I tried those "mini-cats" and still got cel for not enough flow going to secondaries. I tried the 90 degree extenders, they lasted a while but I think it fouled a plug as I eventually got cel but for only one side.
Once I got an epl tune, he blanked out the rears or did his Magic and never had cel's again.

 

Who is your tune by? Or if you plan to get one it can be done in the ECU.

 

if you live in an emissions area and the rear cats are turned off at the dme the car won't pass emissions. thats were the j tubes come into play. i have seen them work and fail.

 

+1 Steve. Regarding the tuning you can target specific codes rather than just turn them off. A nice option if available.

It's very weird to me...in 20+ years on so many different cars I have seen varying results from extenders of different types. With and without mini-cats inside. Sometimes they cause more issues than they solve. The J-tubes seam to be the most consistent though. Points to tuning but even on the same tune it's just not consistent. So many variables...

 

seems like the easiest solution is to get rid of all the emissions testing and let the big dogs eat! no cats no mufflers 3" exhaust!!!!!

 

Ive seen different results as well...
tuning is one option but you can just throw a stock exhaust when you go to do emissions...

 

in a perfect world, would that it could be so...i'm just a little dog but i'd eat from that trough.

every time i see the 3" kline i am wistful

but still cat delete has changed my life i'm so simple lol

( thx sam )
