Product Information

The Borla ATAK Cat-Back is a cat-back exhaust for a 2016-2020 Ford Mustang: GT350, GT500 (2020-2020), replacing everything from behind the catalytic converters back, a bigger system than an axle-back.

Why Upgrade

Per Borla, this system offers:

  • Borla's patented straight-through, multi-core technology, which Borla says unlocks hidden horsepower and increases exhaust velocity
  • T-304 stainless steel construction throughout
  • steel Borla says outlasts the cheaper T-400-series (like 409) steel some competitors use
  • a Merge X-Pipe built into the system, which Borla says adds performance and improves sound
  • no exhaust tips of its own; per Borla's listing this system reuses your factory exhaust tip/bezel instead of shipping a new one
  • mandrel-bent tubing and CNC-controlled manufacturing for consistent flow and a precise fit
  • Borla's electronically-controlled valves, letting you switch the exhaust note between quieter and louder modes rather than one fixed tune
  • a Borla Million-Mile warranty on the system

Fitment Notes

Install and Honest Talk

This is a cat-back system, running from behind the catalytic converters to the tips; it does not touch the catalytic converters either way, so it changes sound and, per Borla, exhaust flow, not emissions equipment. Borla's own listing claims no drone inside the cabin with this system; that's Borla's claim about their own product, not something we've measured ourselves, and drone is notoriously subjective and dependent on your specific car. Borla does not list a dyno figure for this specific system. What else you need: [VERIFY: whether new gaskets, clamps, or hangers are included, and whether it bolts directly to your factory catalytic converter section or needs trimming].

No Robots. Just Car People.

Buying parts for your Mustang or F-150 should not feel like homework. Too many stores bury you in a giant catalog, slap the same distributor description on every product, and leave you guessing whether it even fits.


We do it the other way. We carry the brands you already trust, we tell you what a part actually does, and we give you the truth about the tradeoffs before you spend a dollar. Drone on that exhaust. Ride quality on those springs. Whether you need a tune. The stuff the big catalogs leave out.
