The OE system on many listed vehicles was welded, so replacement may require attention to the surrounding exhaust sections noted in the fitment comments. Confirm rear-position fitment where specified for 2019-2020 Chevrolet Tahoe and 2019 GMC Yukon, and match the application notes for your exact vehicle before assembly.
