MRT 3" Extreme Cat-Back Exhaust System with 4" Black Ops Tips | Fastback 2015–2017 & 2026 Mustang GT (Non-Active)

The MRT 3" Extreme Cat-Back Exhaust System with quad 4" Black Ops tips is made for Mustang GT owners who want the most raw, aggressive tone MRT offers—with zero compromises on volume or visual punch. The stock exhaust setup muffles your Coyote’s potential with cramped piping and oversized mufflers. This system solves that by ditching the restrictions and giving you straight-through flow and a race-bred sound profile, wrapped in a stealthy black finish that turns heads without saying a word.

This is MRT’s loudest tone configuration—no resonators, no crossover, and no gimmicks. Just a hard-hitting, high-flow setup that transforms your GT’s personality with sound and style.

Key Features & Benefits

• 3" Mandrel-Bent Stainless Tubing: Clears the bottlenecks in the stock system for better throttle response and top-end power
• High-Flow, Straight-Through Mufflers: Tuned for aggressive tone with a focused bark under throttle and no-nonsense idle rumble
• Quad 4" Black Ops Tips: Coated in a durable black finish that’s as sleek as it is bold—no polished chrome, just clean aggression
• Drone-Limiting Tuning: Designed to keep cabin noise bearable during long drives despite the volume

• Adjustability: Fixed-fit system designed for plug-and-play install
• Additional Required Components: None — this is a complete bolt-on cat-back
• Part Number: 93U912B
