Exhaust help!!

[Jason Cooley]

Hey everyone, been reading a lot of threads here so I figured I would sign up and reach out. I have a 14 Ram 1500 4x4 with a custom "budget friendly" dual exhaust or at least I thought haha. JBL LT headers, high flow cats, Super 10 series mufflers, really short system. Any who my computer through a code for the secondary stock O2 sensors. Trying to avoid the tuning route if possible and was wondering if there are O2 sensors out there that could handle the increase exhaust flow? Thanks.

Gotta tune it to get rid of codes unfortunately. A good tune will also get you a lot more power.

Agreed.

You could try welding in multiple bungs to see if moving the sensors helps but that's a lot of guesswork and it probably won't work in any event.

never tried this yet buuut worth a shot for $4 you could always try this to try and trick the secondary 02 sensors.

I've never had the non-foulers work on anything in the past longer than a few weeks before codes show up. The only bullet proof method is tuning or plugs and building sim's trick the PCM into perfect catalyst function.

Run o2 defouler like the post above. Make sure you run one with a 90deg elbow like this one. https://www.maperformance.com/produ...gPQXhmxNhwm2NiZiV0-x7rjOfIbDUMoIaAsW4EALw_wcB


The goal is to get the o2 sensor away from the exhaust fumes but still get hot. I ran the 90deg ones in my 370z running just test pipes no cats at all. No error codes when I needed to go to deq take test pipes out and o2s were still good.
