Description

Despite being the least expensive engine option in the 2015-2017 Mustang the V6, with 300HP on tap, is still very potent. Shouldn’t the exhaust note reflect that? Constructed from T-304 stainless steel, the 2015 ROUSH V6 exhaust is corrosion and stain resistant. Constant diameter mandrel bends maintain high flow and reduce backpressure. This axle back system improves sound and performance with single tip High flow Mufflers.

  • Nice upgrade from the stock exhaust.
The sound the axle exhaust from Roush for my 2015 V6 Ford Mustang is a great investment for me. Can't say it is the exhaust for every one but, for me like the sound of it. Even though you need to cut part of your exhaust to fit your new part. Its not a full cat back exhaust. Its an axle exhaust kit.

  • Best exhaust I have ever heard on a ecoboost mustang
Best exhaust I have ever heard on a ecoboost mustang. People mistake my car for a turbo v8 all the time. Make sure to get your resonator deleted. No drone on the highway. Why trust anyone else with an exhuast when Roush is Ford...

  • Aggressive sound but not obnoxious
Love the lower tone. Not obnoxious to piss off neighbors. Low growl, more aggressive sound when get on it than stock.
