I think I saw someone on here say the exhaust from the 11 worked on the 15. Can't remember for sure. Check the part number

I went with kory's and it made a big difference. All stock driving around I got 18mpg and up to 22 on a long interstate trip. When I lifted 7 inches and put 35's on it fell to 13.
Last week I put exhaust and programmer set on the street tune and I'm back to 18. I plan on turning it down to economy and seeing if that helps it anymore!
