"The Boom Tube". Uncork the exhaust of your V6 S550 Fastback Mustang with a MAC Boom Tube Axle-Back Exhaust. This MAC Performance Axle-Back System eliminates the restrictive factory mufflers to reduce back pressure for an increase in both power and sound.

Resonator Tips. Often imitated but never duplicated, the MAC Boom Tube Axle-back Exhaust uses uniquely designed dual wall resonator tips that feature perforated baffles to provide a loud throaty exhaust note without the irritating popping of the imitators.

Durable Steel Construction. Constructed from 2.5" diameter mandrel-bent 304 stainless steel tubing, the Boom Tube axle-back system features polished 4" angle cut stainless steel dual wall tips for impressive muscle car styling and sound.

Cut & Clamp Installation. The installation of this Axle-Back Exhaust system will require cutting and removing the factory muffler assemblies and clamping the new muffler assemblies in place. Clamps and instructions are provided.

Application. This MAC "Boom Tube" Axle-Back exhaust system is designed to fit both 2015-2017 V6 Fastback Mustangs. Not compatible with convertible models.

Please Note. MAC Performance does not make any claims that their Boom Tube exhaust will meet any federal or local noise regulations or laws. Please check your local and state ordnances for installation and usage regulations.

Would this connect to BBK X pipe


Would this connect directly to a 2.5" x or h pipe?


  • The MAC Boom Tube Axle-Back Exhaust is also 2.5 inches in diameter so yes it will work fine.
