Product Information

The Borla S-Type Axle-Back is a rear-section-only exhaust for a 2024-2026 Ford Mustang: GT, replacing everything from the axle back only, the rear-most section.

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
  • black chrome stainless tips
  • 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 2024-2026 Ford Mustang: GT. Does not fit Mustang: Dark Horse, EcoBoost, GTD. Per Borla's own listing: "It fits both the coupe and convertible models."

Install and Honest Talk

This is the rear section only, bolting on behind your factory or existing mid-pipe; 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 specific mid-pipe 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.
