Wj jeep O2 sensors

[billbo90]

I was just wondering if anyone out there are running an after market exhaust system on there 4.7
I put a set of extractors on from the states with 2.5 inch to the muffler 3" back from that my problem is the extractors only have have 1 O2 sensor each side instead of 2. Im been running that for over a year now but god my exhaust fumes are STRONG. I mean they really really stink!!! Just going though a drive though bottlo the clerks always comment on how toxic it smells!. I do have one cat before the muffler but the extractors deleted the pre cats. Just wondering if this is due to only running two O2 sensors instead of 4 or if it could be something else causing this? It runs fine but just stinks any thoughts would be appreciated
Cheers

I would say shes running a little bit rich imo.
I would say the 02 sensors go into the cats and the material in them gets hot and thats how they get there true reading.
Maybe some hi flow cats with holes to suit might fix your problem.
Go to exhaust shop they should help.

Is it producing any errors? I'd be surprised if there aren't any as there are parts of the puzzle missing.

No, no error codes show when i do the ignition test.
