"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.

Straight Piped Sound.

It is an over all good exhaust, it does sound a little funny on a cold start but after warming up you can love that nice turbo hum. Also like when you speed up you can hear the air being forced out the ...

Because this muffler has a muffler delete design, would I lose pressure in the back as if I had a muffler delete or it won't affect the pressure?

  • It's possible that you will lose back pressure, however every Mustang reacts differently in terms of back pressure when changing/modifying exhaust. Unfortunately there isn't a formula to follow when it comes to back pressure and exhaust, which means you may gain a little power, lose a little power, or notice nothing at all, and the only way to find out is to install it.

In the Fitment Section it states "Fits Fastback Models Only" Will this NOT fit a 2015 convertible EcoBoost? If not, why?

Derrick

  • The reason that this will not fit the convertible EcoBoost models is because of the way that the frame of the vehicle is designed.

Would this connect to BBK X pipe

JohnnyJ

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.

    Review from MAC Boom Tube Axle-Back Exhaust (15-17 EcoBoost Fastback)

    Straight Piped Sound.

    It is an over all good exhaust, it does sound a little funny on a cold start but after warming up you can love that nice turbo hum. Also like when you speed up you can hear the air being forced out the exhaust kind of resembling the sound of a turbo on a diesel truck.
