Description
Overview
The Flowmaster Force II Cat-Back Exhaust System is a complete bolt-on upgrade engineered specifically for the 2021-2026 GM Tahoe and Yukon equipped with the 5.3-liter engine. Built to deliver a balanced blend of added performance and refined street manners, the Force II system replaces the restrictive factory cat-back plumbing with high-flow, mandrel-bent tubing and Flowmaster’s proven muffler technology for a noticeably more capable exhaust setup.
At the heart of the kit is the Super 40 Series muffler, tuned to produce a moderate-to-mild sound level that adds character without overwhelming the cabin. Paired with a reflection-style resonator, the system controls interior drone and maintains driving comfort, so your Tahoe or Yukon sounds purposeful on acceleration yet stays comfortable on the highway.
Performance & Construction
The Force II uses 3.00-inch mandrel-bent 409 stainless steel tubing to promote maximum exhaust flow and long-term durability. On the dyno, this system delivers max gains of 6 horsepower and 7 lb-ft of torque at the rear wheels over stock, freeing up the power your 5.3L V8 already has. The silver pipes and black Super 40 muffler are finished off with a larger 3.50-inch polished stainless steel tip featuring an embossed logo, giving the rear of your SUV a clean, custom look.
Fitment & Installation
This cat-back system is designed for the 2021-2026 GM Tahoe/Yukon 5.3L and installs using the factory hanger locations for a straightforward, no-cut fit. All necessary hardware is included, making it an approachable upgrade for the driveway or the shop. The single tailpipe configuration keeps the design clean and functional while the tuned components do the heavy lifting.
