original story- https://www.cherokeeforum.com/f2/gas-mileage-24764/ this thread would not say in cherokee tech long enough for any one to see so i am moving the discussion here.
I have been recently getting bad gas mileage so i have been going though all the possible reasons of why.

I was up under my jeep looking for the 02 sensors when i found a crimp/ dent in my exhaust. I took multiple pictures of the dent and the entire pipe because i would like to know where i can get a replacement pipe. I took pictures and it is very hard to take pictures laying under my jeep but here they are.

this is my first time uploading pics also, so it would be great if someone would tell me how to upload them straight into the forum.

first picture headers to pipe, 2nd headers to pipe, 3rd the dent right which is right after the first picture, 4th the dent, 5th the dent, 6th the pipe coming down, 7th the pipe running to the cat, 8th just before the cat. 9th the cat, 10th random picture
the reason i took so many pictures of the pipe and not the dent was so yall could get the best idea of where the dent is.

is this enough damage to be causing my bad mpg? and does anyone know a good website to get a replacement pipe? cheap?!!!
what caused this?

 

and also i was already planing on upgrading to flowmaster super 40 with 2.5 pieing before i even found this , is this a pipe that i would of had to of up sized any way?
