Hi,

I installed one of these on my 2 door Rubicon JL

https://www.extremeterrain.com/magnaflow-rock-crawler-catback-exhaust-2018-36l-jl.html

After 6 months, I've noticed a significant decrease in acceleration and roughly 2 MPG loss. I've reinstalled the pipes and checked to make sure there were no leaks.

Has anyone else had similar issues or know of how I can fix this? I love the look and would prefer to keep them.

Thanks
