Borla 2018 Ford Mustang GT 5.0L AT/MT 3in Resonator

The Borla Muffler/Resonator is a mid-pipe component for a 2018-2026 Ford Mustang: GT, Bullitt (2019-2020), Mach 1 (2021-2023), Dark Horse (2024-2026), 2.25-inch diameter per the listing, sold as its own part rather than a complete cat-back or axle-back system.

Why Upgrade

Per Borla, this part offers:

• an internal H-Pipe design inside the resonator, which Borla says adds performance and improves sound
• dual 2.25-inch inlets into a dual 3-inch outlet
• compatible with cars either with or without Ford's factory Active Valve Performance Exhaust option, per Borla's listing
• steel Borla says outlasts the cheaper T-400-series (like 409) steel some competitors use
• mandrel-bent tubing and CNC-controlled manufacturing for consistent flow and a precise fit
• a Borla Million-Mile warranty on the part

Fitment Notes

Fits 2018-2026 Ford Mustang: GT, Bullitt (2019-2020), Mach 1 (2021-2023), Dark Horse (2024-2026). Does not fit Mustang: EcoBoost, GTD, GT500, GT350. Per Borla's own listing: "NOT recommended for use on convertibles." Borla's own listing says this part only works with specific Borla systems, never competitor or Original Equipment (O.E.) exhaust: "designed to replace the Merge X-Pipe in select BORLA® Cat-Back systems to dampen the sound." Confirm it matches the exact Borla system you have before ordering.

Install and Honest Talk

This bolts into the exhaust mid-section; it does not touch the catalytic converters, so it changes sound, and per Borla, exhaust flow, not emissions equipment. Borla doesn't say how loud this specific part makes the car; that depends heavily on what tailpipes, muffler, or system you pair it with. Borla does not list a dyno figure for this specific part. What else you need: [VERIFY: whether new gaskets, clamps, or hangers are included, and exactly which Borla system or tailpipe set this part is meant to pair with for your car].
