Great fit and sound!
Verified Buyer — JASON N. | Sep 13th 2026
I have these headers and the Legend exhaust on my 2015 Grand Cherokee Summit 5.7 and absolutely love them. Great sound and an increase in mpg with proper tuning. Not sure if the design has changed but they do indeed fit my Summit edition.
