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

The MRT 3" Extreme Cat-Back Exhaust System with DMS H-pipe is made for Mustang GT owners who want that old-school, deep American muscle tone with a raw edge—and none of the muted factory nonsense. If you're stuck with the stock exhaust, you're leaving sound, flow, and power on the table. This MRT system solves that by ditching the factory restriction and delivering a throatier, louder, freer-breathing exhaust that actually lets your Coyote engine sound like it should.

Compared to stock, this cat-back is an absolute upgrade across the board: better tone, better response, better materials. No flapper valves here—this non-active exhaust is all about keeping it pure and performance-first, no gimmicks.

Key Features & Benefits

• Full 3" Mandrel-Bent Tubing: Promotes max airflow and reduces backpressure so your V8 can breathe easier at WOT.
• MRT DMS H-Pipe Crossover: Provides that classic muscle-car growl and smooths out exhaust pulses for a cleaner tone across the rev range.
• Polished Quad 4" Tips: Gives your rear end a bold, aggressive finish that screams performance—without screaming “afterthought.”
• No Drone Cabin Tuning: Keeps things civil in the cabin so you’re not pulling earplugs on every highway cruise.

Technical Specifications

• Material: T304 stainless steel construction for max durability and corrosion resistance
• Weight Savings: Lighter than the factory system due to high-flow design and efficient tubing layout
• Adjustability: Not adjustable—fixed design optimized for performance and sound
• Additional Required Components: None—this is a complete bolt-on cat-back
• Part Number: 93U914

Who This is For

This system is built for Mustang GT owners running a naturally aspirated or lightly modded setup who want better tone and airflow without going full racecar. Ideal for drivers who don't need the factory active exhaust or don’t want electronics dictating their volume. If you're browsing 2026-2025 Mustang GT cat-back exhausts, this MRT setup belongs at the top of your list—especially if you're looking for that deep, balanced muscle car tone with quad tips that mean business.
