    Better Flow For More Power. Are you looking to add even more power to the rear wheels of your EcoBoost Mustang? Then consider upgrading to a Krona Performance B.A.M.F. Catted Turbo-Back Full Exhaust System. This Krona Performance Exhaust eliminates restrictions by replacing the factory catalytic converter and mid pipe resonator with a High Flow Race Catalytic Converter and a 3" to 2.5" Y-Pipe, respectively. Together with mandrel-bent 2.5" tubing and a pair of high flow straight-through mufflers this Krona Turbo-Back will significantly improve the exhaust flow of your Eco-Boost Mustang for more power you can feel across the power band.

    The Sound of Power. Not only will a Krona Performance Turbo-Back improve the power and performance of your EcoBoost Mustang, but it will also improve its sound as well. A Krona Full Exhaust will give your turbocharged Mustang a much more aggressive sound without any annoying interior cabin drone or harsh, ear splitting rasp. This Turbo-Back Exhaust is ideal for those considerate Mustang owners who don't want to upset their neighbors while out enjoying a spirited drive around town.

    Full Exhaust Kit. The Krona Performance B.A.M.F. Full Exhaust Kit is a complete system from downpipe to exhaust tips. This kit includes a 3" Downpipe with a High-Flow Race Catalytic Converter, a 3" to 2.5" Y-Pipe, and a 2.5" exhaust with straight through mufflers. The mufflers feature mirror polished double wall rolled 3" tips that have been laser etched with the Krona Performance logo for impressive good looks.

    B.A.M.F. (Bolt-on And Modular Function). By being a modular design you can pick and choose which Krona Performance exhaust components to install based on your needs or budget. You can install a full turbo-back system in one shot or build one over time as money allows. It does not matter if you choose a Downpipe, a Cat-Back, or a full Turbo-Back, all of the correct adapters are included so that all these kits will work together with both factory and Krona exhaust systems.

    Stainless Steel Construction. Krona Performance proudly manufactures their exhaust systems right here in the USA. This Turbo-Back is constructed from 0.065” thick mandrel bent T304 stainless steel tubing for superior strength and long lasting corrosion resistance. The Downpipe features two standard O2 fittings for both upstream and downstream O2 sensors.

    Lightweight. Weighing in at approximately 55 lbs, the Krona Performance B.A.M.F. Turbo-Back is 25 lbs lighter than the stock exhaust system. This makes the Krona Turbo-Back a great choice for track and drag racers looking to shed unwanted weight in the pursuit of quicker times.

    Direct Bolt-On Installation. Krona Performance engineered their B.A.M.F. Turbo-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 three hours with just basic hand tools.

    Recommended Upgrade. Even though a re-tune is not required for operation, AmericanMuscle recommends a custom tune with a Handheld Tuner. By reprogramming the vehicles computer (ECU) you will get the best possible power and performance increases from this Krona Performance exhaust system.

    Application. This Krona Performance B.A.M.F. Turbo-Back Catted Exhaust System is specifically designed to fit 2015-2019 EcoBoost Mustangs without the Active Valve Exhaust.

    It says it will fit a 2015 to 2019 Ecoboost Mustang Fast Back but it says it won't fit my 2018 Ecoboost FastBack? is this an error?

    • The Krona Performance B.A.M.F. Catted Turbo-Back Full Exhaust System will fit the 2018 Ecoboost Fastback Mustang (Not equipped with Active Exhaust).

    Shouldn't this be listed as for off road use?, when it is guaranteed to throw a CEL for cat code 420, which can only be supressed by tuning. Also AM/BAMA refuse to make one of their tunes suppress this code.

    Will this product work with an aftermarket chip such as JMS boostmax?

    • The Krona Performance B.A.M.F. Catted Turbo-Back Full Exhaust System can be used with the JMS Boostmax and all other throttle controllers.

    will this paaa virginiq emmisions?

    • Due to its use of a high flow catalytic converter, this will not pass emissions in many states. unfortunately we are unfamiliar with the laws in Virginia, and would be unable to determine if this would pass.

    Is this exhaust system legal in Texas? I have been told my professional shops that they will not install it for me because they are saying it is illegal... that its not catted....

    • It can honestly vary per state. We highly recommend checking with your state ordinances or a local shop to confirm if this part is legal for use in your state.

      NOT street legal

      This product would get 5 stars except for its inaccurate advertisement which will cost me a lot of money to remedy. This product is NOT listed as off-road only, just possibly failing emissions in some states and non-carb....vs the catless which is clearly labeled as off-road only. The problem is, this product causes the CEL cat 420 code to pop, which will fail emissions in any state that has emissions tests, a step beyond 'may not pass'. The only way to make this pass in ANY state with emissions would be to illegally supress the codes. Many tuners will do this - BAMA, will not (purchased CAI with bama lifetime tunes). My choices are go back to stock, waste $1500 in this exhaust, get something like Kook's green 49 state cat welded in for $800 install, spend however much to downpipe swap every 2 years for emissions, or go to a local shop with cob that will charge ~$500 for a dyno tune that will supress the code (and thats after spending over $500 separate for a cob hand tuner!). PS: Can't trust AM product QandAs, one of BAMAs employees told me that they don't really know what they're talking about, when I was discussing a WGA that also went into this setup.

      Sounds good when you have power behind it

      This system combined with 400 hp, makes it sound like a Ducati motorcycle. No rasp, no drone at any speed, has a nice low hum. If you want power but don't want to upset the neighbors or draw attention to yourself, this is the perfect "sleeper" setup. All the power, none of the loud noise. Don't get me wrong, it sounds sweet, but when you try to make a 4 cyl sound like a v8 it's going to sound stupid, that's why I avoided the other brands that boast about making a loud sound, yeah they're loud and sound like a chainsaw, sorry but to me they do, and I don't want that. This makes your ecoboost sound like a powerful big 4 cyl, not a tuna can import with a chainsaw engine.

      Performance at its best!

      If you want that loud, deep.. bleb bleb bleb bleb tone to your ecoboost then this performance exhaust definitely gets the job done! This will definitely wake your neighbors lol! Also this exhaust has no drone(resonance in the cabin) to it! Work amazing at 2500RPM, around 65-70 mph.
