Product Information

The Borla Atak-S Cat-Back is a cat-back exhaust for a 2015-2017 Ford Mustang: GT, 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
  • bright chrome stainless tips (4-inch)
  • mandrel-bent tubing and CNC-controlled manufacturing for consistent flow and a precise fit
  • a Borla Million-Mile warranty on the system

Fitment Notes

Fits 2015-2017 Ford Mustang: GT. Does not fit Mustang: EcoBoost, GT350, V6. Pipe diameter: 2.5 inch, per the listing.

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. Expect a louder exhaust note than stock, with some drone at certain highway RPMs possible, which is common for aftermarket exhausts. 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.
