Anyone running aFe Axle Back Exhaust?

[jlroman2]

Is anyone running this axle back exhaust? I recently installed it like 3 weeks ago and have noticed a significantly reduce in MPG. Also in acceleration. I feel like I have to step harder and it doesn’t free flow right out. It feels like if I have back pressure. Thought it would be a complete opposite experience?

This shouldn’t be causing any of those issues, tbh the only issue this muffler delete should cause is hearing loss.

Exactly, I’m trying to figure out what’s going on

Can you go over how you installed it? Take a look at your o2 sensors and your catalytic converters maybe it was damaged. I would also throw the old muffler back on, and see if that returns the situation back to normal. More than likely these issues are a coincidence rather than caused by the muffler delete, you have other issues going on. If you have a obd tool I would check for codes and if you have warranty let the dealer check it out. Sometimes they leave packing material in the pipe did you check for that prior to installation?

I never really looked into the problem. I guess I just got used to it. Jeep also is way different now, so many factors. I did have problems with the O2 sensors so it might not have been because of the muffler delete. Sounds pretty aggressive and people always tell me how they love how it sounds. At $150, just go for it. If you don't like it, I am sure somebody will buy it.
