The MagnaFlow 16672 is a Street Series cat-back exhaust for the 5.3L V8 in 2007-2008 Chevrolet Tahoe and GMC Yukon models. The fast-flowing, mandrel bent 3in. main piping and 1 Straight-Through mufflers ending in a Single Passenger Side Rear exit give it a distinct, deeper tone than factory exhaust. The manufacturer also describes it as durable corrosion-resistant stainless steel construction made with CNC robotic manufacturing. Choose it over a cheaper mild-steel kit when you want a system that resists rust through winters and road salt, and a moderate exterior volume that stays mild inside the cabin on daily drives.
Fitment is the first thing to verify. The manufacturer's application list pairs this kit with 2007 and 2008 Tahoe and Yukon models, but the product title names only the 5.3L. Confirm your engine before ordering, since the list also includes 4.8L entries. This is a bolt-on cat-back, so it replaces the stock piping from just behind the catalytic converter rearward. Owners searching for a 2007 Tahoe 5.3L stainless cat-back, a 3-inch Yukon exhaust, or a bolt-on SUV exhaust with a passenger-side rear exit will find this kit matches those needs.
The manufacturer's application list includes both 4.8L and 5.3L entries for 2007-2008 Tahoe and Yukon models, but the product name references only the 5.3L. Confirm your engine size with the manufacturer before ordering.
No. The manufacturer states that neither a gasket or seal nor a mounting bracket is included with the kit, so plan to source those separately.
This is a bolt-on system that replaces the stock exhaust from near the catalytic converter back, so the front section stays in place. Because gaskets and mounting brackets are not included, inspect your factory hangers and seals before starting. Install difficulty, required tools, and torque specs were not confirmed in this research, so review the manufacturer's install instructions before you begin.
