Put em on last night, but now truck is weak, and pops (some from the O/R Y), but LOUD pops.
If I were to go have the cats I have sitting here put on, and put the rear O2's back in, it will cure it, right?

Im used to my Dodge, when I put headers on it, it woke it up some, and I had no problems...

Help? Its almost at the point of the driveability is horrible, and I dont want to take it on the road.

RIght now is Pacesetter LTs, an offroad Y, and a flowmaster 40, dumped before the axle.

 

Rear 02s only let the PCM know that the cats are working right..
Get a tune and be done with it..

 

most tunes offer free updates anyway. look up blackbear performance

 

Its my DD, I kinda need a NOW fix.

Tuning can be taken care of right down the road at TSP, I just need to see which one will fix it for cheaper.

 

And TSP is booked solid. great.
Im gonna take em back off I guess.

 

Did you crack a spark plug when you installed the headers?

 

Thats what i had starting thinking..
Just cause you put LTs on, its still goin to run decent, shouldnt do what your explaining.

 

putting your cats back in your ORY isnt going to stop the popping. you need to get your re-tune and see if that fixes it.

 

Pull all the spark plugs and check the porcelin, also make sure all the wires are pushed in FULLY on the plug and on the coil.

I ran my longtubes untuned for about a week, and i never experianced any loud popping or any driveability issues at all. I did pick up a noticeable amount of power after the tune though

 

I pulled all of them but the front two.
I can re-check them, and hopefully that fixes the problem.
