2015-2016 Ford Mustang Borla 2.3L AT/MT Rear Section ATAK Exhaust

The Borla ATAK Axle-Back is a rear-section-only exhaust for a 2015-2023 Ford Mustang: EcoBoost, V6 (2015-2017), replacing everything from the axle back only, the rear-most section.

Manufacturer-supplied Borla details include Borla's patented straight-through, multi-core technology, which Borla says unlocks hidden HP 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; mandrel-bent tubing and CNC-controlled manufacturing for consistent flow and a precise fit; a Borla Million-Mile warranty on the system.

Fits 2015-2023 Ford Mustang: EcoBoost, V6 (2015-2017). Does not fit Mustang: GT, Mach 1, GT500, Bullitt, GT350. Per Borla's own listing: "EXCEPT vehicles with Active Valve Exhaust (4 tips).".

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. 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.

Listed specifications include Type: ATAK Axle-Back; Material: T-304 stainless steel.

Free US shipping over $99

Orders over $99 ship free by ground to the lower 48 states. Alaska, Hawaii and Canada are not included; shipping to those addresses is calculated at checkout. Some oversize or heavy parts (long-tube exhausts, bumpers, full lift kits) go freight instead of parcel: free to a commercial address with a loading dock, and residential freight delivery carries an additional charge.

When it ships

Parts ship direct from the distributor warehouse that stocks them, so dispatch timing depends on the part, not on a single cutoff. You get a confirmation with tracking as soon as it leaves, and tracking shows the delivery estimate for your address. If a part is backordered we email you an expected availability date.

Report a short shipment or shipping damage within 5 business days of delivery. For a packing error, send us the date or package code printed on the label along with the part number so we can trace it with the warehouse.
