About Borla S-Type Exhaust

Borla’s S-Type Cat-Back Exhaust systems are designed to give your Mustang an aggressive muscle-car tone without drone thanks to the straight-through flow design mufflers. In addition to great sound, the S-Type Exhaust system will bolt up to your factory catalytic converters to keep your Mustang 50-State emissions compliant!

Along with the S-Type Mufflers, this system includes Borla’s X-Pipe to increase the sound, tone, and performance from your Mustang’s 5.0. You’ll find yourself with a raspier, racecar like sound that is amplified by the Borla S-Type Mufflers.


Borla S-Type Cat-Back exhaust systems are manufactured from T-304 Stainless Steel with 2.5″ mandrel bent tubing and feature the Borla X-Pipe, (2) over-axle pipes, (2) S-Type Mufflers, and (2) eye-catching 4 in. angle-cut rolled Stainless Steel polished tips. The S-Type Mufflers feature an embossed Borla logos which look great when in view – whether your car is on a lift, or someone just happens to look up your Mustang’s backside.

This system is designed to replace your Mustang’s entire exhaust system from the catalytic converters on back, including the replacement of the factory resonator.
