The Sound of Power. Give your 2015-2017 Coyote powered Mustang a more aggressive exhaust note by upgrading to a Krona Performance 3" Cat-Back Exhaust System. Engineered using Helmholtz's Theory of Tone, this Krona Cat-Back incorporates both active and passive resonators to add a more intimidating sound to your GT without any annoying cabin drone or harsh, ear splitting rasp. A Krona Performance Cat-Back is perfect for those who don't want to upset the entire neighborhood while out enjoying a cruise around town.

Improves Exhaust Flow. Not only will a Krona Performance Cat-Back improve the sound of your V8 powered Mustang, but it will also improve its exhaust flow as well. This Cat-Back features a high flow mid pipe resonator, that eliminates the bulky factory unit and replaces the restrictive 2.5" factory piping with mandrel-bent 3" tubing. Together with a pair of high flow straight-through mufflers this Krona Cat-Back will significantly improve the exhaust flow of your GT Mustang when compared to the stock cat-back system.

Stainless Steel Construction. Krona Performance proudly manufactures their exhaust systems right here in the USA. This Cat-Back is constructed from 0.065” thick mandrel bent T304 stainless steel tubing for superior strength and long lasting corrosion resistance. The included straight through mufflers end with mirror polished double wall rolled 4.5" tips that have been laser etched with the Krona Performance logo for impressive good looks.

Direct Bolt-On Installation. Krona Performance engineered their Cat-Back to be a direct bolt-on upgrade replacement for your Mustang's factory exhaust. There is no cutting or extra modifications required. Installation of this Krona Performance Exhaust can be completed in about a two hours with just basic hand tools.

Application. This Krona Performance 3" Cat-Back Exhaust System is specifically designed to fit 2015-2017 Fastback GT Mustangs equipped with the DOHC 5.0L V8 Coyote engine. Not compatible with Convertible models.

I'm installing Pypes off road headers with 3" pipes from the header collector to the resonator. The photo appears to have step up pipes from the factory 2.5" system. Will this 3" header system system couple up properly to the Krona resonator pipes without any adapter piping?

  • The header system will be able to couple up to this Krona PErformance 3" cat-back without additional adapters or piping.

    Very Nice Exhaust

    This Krona cat back is a very nice setup. Installs easily thanks to its design. Took my self less then an hour on Jack stands in my garage. Takes longer to remove the stock system then to install the Krona Parts. Welds are all top notch as is the construction of everything else. Love the 4 1/2" tips that are completely adjustable to get them to your liking. The exhaust note/tone is perfect, I think. Very nice deep idle, that gains in tone and aggressiveness as you increase throttle. Perfect for something that is not track toy, could very easily daily drive with this setup. It is non offensive at highway speeds in the S550. Waiting patiently to add a set of their headers to it once they come out.

    Wow

    Installed it in about a hour with my brother with zero problems. Everything fit together perfectly. Loved the craftsmanship on this exhaust and the tips look amazing installed, really fills out the exhaust area. I will say it's much louder then the AA review said it was but mostly not in a bad way and there is deff a decent amount of cabin noise from it. I even get a bit of drone around 65mph but it's very controllable just slowing down or speeding up a slight bit stops it pretty quickly, I'm hoping it may just need a few more miles on it to break in possibly. But the exhaust note itself is easily the one of if not the best I've heard, no raspiness, very deep rumble and when you do hit those high rpms it's tone goes up quickly but not in a tin can way. Deff glad I went with this exhaust over a louder rated exhaust because that would just be insane to daily drive. This exhaust will deff wake the neighbors while coming or going unless you coast home. It is remarkably quiet though at low rpms

    Krona Performance: Turning Heads

    I get complimented on this exhaust constantly. It's honestly one of the best sounding kits available and made to the highest level of quality. The owner - Matt Printz - is such a standup guy as well. I've had the pleasure of working with him since the Krona Ecoboost exhaust came out and I'm very happy I stayed on-board once I got my GT. The sound this thing makes is fantastic. No drone whatsoever, WOT screams like a Corsa, but cruising leaves you with this nice grumbly popping tone like you'd hear from a Solo kit. To me, it's the best of both worlds without sacrificing anything. Cannot wait to get a set of Krona 1 7/8 Headers (coming Q4 '16) next... [Look up Krona Performance Catback on YouTube to see a few sound clips I posted!]

    GREAT SYSTEM!!!

    I have been running the Krona 3in system for bout 2 months now an couldn't be more happier with the setup. The time that was put into developing this system was well worth the wait. The quality of the system is great, the system bolted right up with no problems, comes with all the clamps and hardware you need. Once I install my krona kit I fell in love all over again with my car, the sound is amazing, I am running Cat-less longtube headers and have no drone at all which is what I wanted, the system sounds great while cruising and am still able to talk to passengers and on the phone. As soon as you down shift and go WOT it is like waking up a monster, amazing loud and sounds great. The 4 1/2 inch chrome tips really make the rear end pop. All in all I definitely got what I was looking for when I installed the exhaust and couldn't be more happier with the Krona system.
