Description

Overview

The Flowmaster Force II Cat-back Exhaust System is engineered for drivers who want a noticeable performance upgrade without an overwhelming exhaust note. Built for the 2015-2020 Chevy Tahoe and GMC Yukon equipped with the 5.3L engine, this bolt-on system delivers the mild-to-moderate sound level that the Force II series is known for, along with the flow and durability you expect from Flowmaster. It’s a complete, ready-to-install kit that includes the muffler, tubing, tailpipe, tip, and all necessary hardware.

Performance and Sound

At the heart of the system is a Super 50 Series muffler, tuned to produce a smooth, moderate tone that stays refined at cruise and comes alive under acceleration. Every section is crafted from stainless steel with mandrel-bent tubing, ensuring consistent diameter through the bends for maximum exhaust flow. The 3.00-inch inlet feeds into a mandrel-bent 3.00-inch stainless steel tailpipe, keeping gases moving efficiently from the muffler to the exit for real performance gains.

Fit and Finish

The system finishes with a polished 5.5-inch x 3.5-inch oval stainless steel tip featuring the Flowmaster logo embossed directly into the metal for a clean, factory-plus appearance. Flanged mounting connections make for a straightforward, secure installation, and the silver stainless pipes paired with a black muffler give the setup a durable, understated look under your Tahoe or Yukon.

Key Highlights

Emissions and Warranty

This Force II cat-back is an emissions-legal, CARB (California) compliant system, making it a smart choice for enthusiasts in states with strict emissions standards.

Fitment Notes

Designed specifically for 2WD applications on the 2015-2020 Tahoe and Yukon with the 5.3L engine. This system does not fit the Yukon XL, so confirm your vehicle before ordering.
