Redneck, I think your solution of the Borla long tubes was a good one. The bungs are there for all 4 O2 sensors. It also would be a fair pre-sales support question to ask them if this set up would throw any DTCs or the check engine light. It also looks as if there is enough space after the collector and before the second set of O2 sensors to weld in after market cats.

It won't be the cheapest solution, but probably the best. If you don't want to do that, then generating a stable O2 sensor reading using an O2 simulator is your best bet.

It all depends on the vehicle that you are working on, alot of the German car (05 and up) upstream sensors actually do look at the downstream sensors:yup:

well i just got back from removing the last 3 cats and 2 ended up being bad . i did the non fouler trick . i have not erased the codes yet to see if they come back ( fingers crossed ) one cat was already completely hollow and the other was half empty . i would never remove these for a performance gain . the only reason for removal was because of the damage from the crash . i installed a long glaspack before the factory muffler so it still sounds stock . it sounded like a honda wit a fart pipe after the cats were removed LOL:wink:

Magnum makes an O2 eliminator that covers all 4. I have an 09 the cat is burnt and the error codes are throwing my Jeep into limp mode.
