ATAK AXLE-BACK EXHAUST SYSTEM
2024-2026 Ford Mustang GT S650 | 5.0L Coyote V8 | Non-Active Exhaust | Black chrome Tips
ATAK (Loudest)
T-304 Stainless Steel
2.5" / 3"
4" Quad Black chrome
WHAT THIS DOES
The axle-back is the rear section only — mufflers and tips. Keeps your factory mid-pipe and cats completely untouched. This is the fastest bolt-on exhaust upgrade for the S650 GT. Unbolt two clamps, slide the stock mufflers off, bolt these on. Under an hour in a driveway.
ATAK is the loudest exhaust Borla makes. Aggressive V8 bark at startup, deep rumble at cruise, full scream at wide-open throttle. Borla's Polyphonic Harmonizer inside the muffler kills highway drone without restricting flow.
Built for GTs WITHOUT factory Active Exhaust — no active valve wiring needed. Fits both coupe and convertible. Same part number, same install. The quad 4-inch black chrome tips fill the rear bumper cutouts on both body styles.
WHAT IT'S MADE OF
T-304 stainless steel, not the T-409 that cheaper brands use. Won't rust, pit, or discolor. Every bend is mandrel-bent (not crush-bent) for smooth flow, and each system is CNC-machined for bolt-on fitment. Made in the USA. Ships at 32.2 lbs boxed (45 x 11 x 21 inches).
