Catback exhaust issues?

[westtexas82]

So I’ve put Afe catback exhaust on a 25 Gladiator and a 25 Rubicon and seem to both start driving different as in injection issue and rougher shifts. Has anyone had issues like that? Will the computer adjust to the new fuel/air/gas ratio that may have been caused if it’s that?

Injection issue? Can you be more specific? Are you getting a check engine light? I put the AWE 3" trail edition on my 22 and only have good things to say about it.

I’m not sure what it is but it’s happen in both vehicles after catback installation. Didn’t know if that changed the timing or injection. I’ve had exhaust and everything you can bolt a car before and never this issue without a tune.

I have a 22 2.0t, with the black afe cat back, no issues with shifting or engine. Did you change the air intake as well?

 

[westtexas82]

No it’s stock intake

That’s really strange, sorry, I have no idea what would cause the issue besides some sort of restriction or blockage in the tubing / muffler or a flow problem in the resonator.

All the 3.6 have a 'hiccup' around 2-3k rpm, is this what you're talking about?

Yes seems to come a slower leisurely drive around 25 mph between 2-3k rpm.
