Give your 2015-17 5.0L V8 Mustang a more aggressive sound and a boost in performance with the ROUSH Dual Tip Exhaust

The ROUSH Twin Tip Axle Back Exhaust Systems are constructed of corrosion resistant T-304 stainless Steel and are mandrel bent. Mandrel bending maintains a constant inner diameter with no kinks or creases. This improves exhaust flow and reduces backpressure in the system. This system includes single tip High Flow mufflers that improves the stock sound of the Mustang V8 and increase air flow for greater performance and fuel efficiency.

As this is an Axle-Back System, it produces a great exhaust tone, and will not cause droning - which is commonly seen on Automatic Mustangs with Catback Systems.

This system will produce louder deeper exhaust tone, with a healthy V8 burble at idle, building to a powerful roar at high revs.

Roush rumble

The rumble when you start up the GT is awesome. The note made by the Roush makes you want to drive at every opportunity.

Tha Roush has certainly livened up the note from the Mustang. A nice and deep burble at idle building to a full throated when you bury the right boot. Just what a Mustang should sound like.

perfect sound for me

Did a lot of research and listened to many sound clips before ordering this system. In my opinion its the best sound that you can do without replacing the whole system and to be perfectly honest sounds just as aggressive - quietish if you need it and loud when you want it -highly recommend -easy enough to fit just take the time to file black paint back also -

There is NO DRONE from these mufflers and they sound great. Put your foot down and the car roars or just cruise along fairly quietly.

Massive improvement on the factory exhaust. The exhaust note is what you’d expect from a Mustang V8 minus the drone.

Roush Axle Back

Great product easy to install much louder than stock . Probably a bit too loud for me and definately for the Mrs. I might put a 9 inch resonator on and I reckon it will be just about right Hoping any way If you want the sound these axle back are sweet at low rev but howl at high revs If I was 21 they would be perfect !!
