Description
Overview
The Flowmaster Outlaw Axle-back Exhaust System is a race-oriented upgrade engineered to replace the original rear-mounted mufflers located behind the rear axle. Built for the enthusiast who wants the most aggressive setup available, this Outlaw-series system uses factory-style connections for a clean, purpose-built fit while transforming both the sound and performance of your vehicle. If you’re chasing an ultra-aggressive attitude from your exhaust, the Outlaw delivers exactly that.
Aggressive Sound, Serious Performance
At the heart of this system is the Flowmaster Outlaw-series muffler, tuned to produce an ultra-aggressive interior and exterior tone that leaves no doubt about your vehicle’s intentions. This isn’t a subtle upgrade — it’s built for drivers who want their engine heard. Beyond the commanding sound, the Outlaw system carries the same performance-focused benefits found across Flowmaster’s lineup, including improved throttle response, added power, and better mileage.
Configuration & Design
This axle-back configuration is designed for 2WD applications and features a dual tail pipe layout for a bold rear-end presentation. The system runs a 2.50-inch inlet diameter and includes the Outlaw-series muffler in the kit. Pipes are finished in black for a stealthy, purpose-built look that complements the aggressive character of the system. As an axle-back setup, it replaces the components behind the rear axle using factory-style connections, making it a straightforward path to a major sound and performance improvement.
