Better Flow For More Power. Unleash the beast lying dormant in your 2015-2019 Turbocharged Mustang by upgrading to a Krona Performance Off-Road Down Pipe. This Krona Performance 3" Down Pipe is much larger than stock and completely eliminates the restrictive factory catalytic converter to drastically improve exhaust flow. By improving exhaust flow you will be able to liberate all the horse power and torque that is caged up in your EcoBoost's 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 Off-Road 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. Off-Road 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.

Calibration Required. Installation of this Krona Performance Off-Road Down Pipe will require the use of a Handheld Tuner to reprogram the vehicles computer (ECU) for operation. By reprogramming your Mustangs ECU you will be able to realize the full power potential that this exhaust system have to offer.

Not CARB Certified. This Downpipe is not CARB certified, therefore it is not legal for use in California or any other state adopting California emission standards. Not legal for use on pollution controlled motor vehicles; intended for off road use only.

1 Top Rated Question

Will this downpipe fit, without an adapter, with the RTR Tactical exhaust on the 18 EcoBoost?

  • Unfortunately, this downpipe was designed to work with a 2.25-inch exhaust and will not fit with the RTR exhaust due to it being a 2.5-inch exhaust. If you were to use this part with the RTR exhaust, you would need an adapter that steps down to a 2.5 inch instead of the 2.25 inch.

    Krona Turboback

    I installed the Krona Turboback on my ecoboost with me and the help of one of my friends. It was a tough install to do but every downpipe is difficult. That being said, the quality and fitment on the Krona downpipe is fantastic. Very nice stainless steel, solid welds, and everything lined up beautifully. Definitely got my ecoboost running how I wanted it after I tuned it. And the sound was full of pops and burbles. Good stuff.
