I discovered a stupid mistake I made while installing my turbo. I pushed the exhaust extension pipe too deep into the stock cat-back exhaust pipe. The whole stock cat-back system was pulled forward when I tightened the extension pipe to the down pipe, which caused this to happen:



The hump in the exhaust over the rear axle is out of alignment now, and the rear track bar crushed the exhaust a bit when my suspension bottomed out at some point (probably that day I spent off road soon after the install).

I wonder how much power I'm losing because of this exhaust constriction.

Anybody have ideas for the cheapest way to fix this? I've already posted in the "wanted" section of a few forums for stock exhaust take-offs.

I could be wrong...but I think they come that way stock. Mine brand new had the same bend in it just over the axle prior to doing any off-roading...again, I could be wrong.

Picture updated to highlight the damage. The large bend over the axle is normal. The flat partially crushed part is not normal.

You could always just cut the exhaust off a little farther upstream of the bend for free if you don't mind the increased noise. Or go to a muffler shop and they can bend you some pipe and weld it in for cheap. Or cut that little bit out and put some flex pipe in its place.

Your exhaust is out of alignment, but the photo you're showing in post #1 of the "crushed" pipe circled in yellow was manufactured that way. All JK's have it. Only yours is now misaligned.

Yup, 100% normal. I have the same "dent" on my 2014 Rubi.

Oh, wow. Thanks for the info everyone. I still wonder how much power could be freed up with an after market cat-back system without a "dent", especially with forced induction. But I feel much better knowing that I don't have to replace anything now :)
