    Does this fit the US convertible 2.3L s550?

    • This exhaust will not fit a 15-18 convertible model due to the different bracing.

    • We do not currently have any sound clips for this at the moment but we very well may in the near future.

    Will installing this exhaust void the warranty I have on my 2017 Mustang Ecoboost

    • This exhaust shouldn't void the warranty on your Mustang, but we would still recommend contacting Ford directly to see how this could affect your warranty.

      They sent me 2 drivers-side mufflers

      Looks great and sounds great, but the passenger-side muffler's exhaust hanger exactly matches the drivers side. It still fit on the car but the hanger is poking out of the bottom of the car. Right now I have it hung up by some cable just so it doesn't sag

      Understated deep tone

      Good sound-gives a low rumble on accel and decel. As mentioned in other posts, it won’t upset the neighbors. Brings ecoboost up a notch on the fun factor.

      Almost perfect!

      I’ve had this exhaust for a solid 20 minutes and I’m already in love. Makes your car sound so much better. Mine is paired with a race downpipe by MBRP as well, and it’s added a nice tone to the exhaust note. No drone what so ever and it even pops and crackles when you down shift. The only complaint I have was how tight of a fit the exhaust was. There was hardly any clearance at all. Also when I recievwd the pipes the flanges were slightly bent. But other than that I have absolutely no complaints

      Amazing Exhaust System

      Super easy install, only took a couple hours. A lot louder than I expected but it is a really nice low tone! The best bang for your buck in my opinion!

      Ecoboost is Alive Now

      I'm very please with this kit. The fit and finish was excellent and the install was headache free. Took me about 2 hours and that was with the car on jack stands. Had I had an overhead lift, it would have taken maybe and hour. Now my Ecoboost sounds like it should.

      Nice sound

      Nice exhaust for the price can hear the turbo a lot more now through pipes. Only issue i had someone welded the exhaust hanger backwards had to take it to a local shop to get it ground off and rewelded the correct way no big deal cost $20 just make sure before install the hangers by axle point towards front of car the hangers by bumper face towards back of car.
