    Better Flow For More Power. Uncork the genie living your 2015-2019 EcoBoost Mustang by installing a Krona Performance Catted Down Pipe. This Krona Performance 3" Down Pipe is much larger than stock and features a high flow race catalytic converter to significantly improve exhaust flow. By improving exhaust flow you will be able to release all the horse power and torque that is bottled up in your turbocharged 2.3L engine for an increase in performance that you can feel across the power band.

    The Sound of Power. Not only will a Krona Performance Down Pipe improve the power and performance of your EcoBoost Mustang, but it will also improve your Pony's sound as well. A Krona Catted Down Pipe will give your turbocharged Mustang a much more aggressive sound when compared to the original factory down pipe.

    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 available 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 Down Pipe is constructed from 0.065” thick mandrel bent T304 stainless steel tubing for superior strength and long lasting corrosion resistance. Krona's Downpipe features two standard O2 fittings for both upstream and downstream O2 sensors.

    Direct Bolt-On Installation. Krona Performance engineered their B.A.M.F. Catted Down Pipe 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 Down Pipe.

    Application. This Krona Performance B.A.M.F. Catted 3" Down Pipe is specifically designed to fit 2015-2019 EcoBoost Mustangs equipped with the turbocharged 2.3L in-line 4-cylinder engine and a 2.25" cat-back exhaust system.

    5 Top Rated Questions

    I have the Magnaflow competition cat-back. Will this downpipe fit my exhaust?

    • Unfortunately this down pipe will not fit as it requires a 2.25" cat-back exhaust system and the Magnaflow is a 2.5".

    Does this pass emissions? And will this fit with a borla axle back stinger exhaust?

    • The Krona Performance B.A.M.F. Downpipe will pass emissions in some states, but not others. We recommend checking with local emissions inspectors to verify legality for your area.

    Does this fit roush quad tip exhaust system?

    • The Krona Performance B.A.M.F. Downpipe - Catted will connect to your factory cat-back exhaust, and would not directly connect to the Roush Quad Tip Active Axle-Back Exhaust, Item 389791 and Roush Quad Tip Passive Axle-Back Exhaust, Item 388836. As long as you have a factory cat-back exhaust or similar, you may install both the downpipe and the Roush Quad Tip exhaust without interference. I have attached both of the axle-back systems for reference:

      Krona Downpipe for Brutus

      The Krona downpipe has excellent craftsmanship. But the real winner is the performance boost. This downpipe really woke my Ecoboost Mustang up all across the power band. The sound from this downpipe combined with my Gibson exhaust is awesome. The woman who owns the detail shop was going nuts when I pulled in the bay with Brutus the Mustang. She has a Focus RS and was just ecstatic over the sound from the Mustang exhaust and downpipe. I told her it was the Krona Catted downpipe that put the sound over the top.
