Borla S-Type on the 2024+ S650 Mustang EcoBoost
WHAT THIS DOES
The fastest bolt-on exhaust upgrade for the S650 EcoBoost. The axle-back is the rear section only — mufflers and tips. Keeps your factory mid-pipe and cats completely untouched. Unbolt two clamps, slide the stock mufflers off, bolt these on. Under an hour in a driveway.
S-Type tuning sits between stock and aggressive on volume. Gives the 2.3L turbo a deeper, more refined tone without the rasp that plagues most four-cylinder exhausts. Borla's Polyphonic Harmonizer inside the muffler kills drone without restricting flow. Comfortable on a long highway drive.
Fits both coupe and convertible. Same part number, same install. The quad 4-inch carbon fiber with black anodized base tips fill the rear bumper cutouts on both body styles. No Active Exhaust on EcoBoost models — this is a direct bolt-on with no electronics to worry about.
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.
