I found this video which compare all exhausts for Jeep Gladiator Very helpful if you are thinking which exhausts to upgrade and find the best sound you like. You can click on the video for all exhausts timestamps & links Which exhaust you liked the most?
Funny, after listening to them all the stock doesn't sound too shabby. None of them really blew me away. I don't think I'd spend the money on the upgrade until the stock one needed replacing.
