This is a OEM stock exhaust system that was taken off a 2023 Chevy Suburban and will easily fit the same vehicle or a GMC Yukon XL. Keep in mind that this is for the longer wheelbase vehicle so if you plan on installing this for a Chevy Tahoe or a GMC Yukon, certain modifications will have to made. Same goes for if you are installing for the 5.3L engine it is possible to install this exhaust for that engine if you do the right modification when it comes to the bumper as well the stock exhaust system.
