KTM 390 Duke 2019-

Transform your ride with our premium ktm performance superbike exhausts, specifically engineered for the KTM 390 Duke 2019 onwards. This exceptional exhaust system delivers a remarkable blend of performance enhancement, weight reduction, and aggressive sound character that perfectly complements the Duke’s street-fighter DNA. Whether you’re carving through city streets or attacking mountain passes, this exhaust upgrade represents one of the most effective modifications you can make to your KTM 390 Duke.

Premium KTM Performance Superbike Exhausts Engineering

Our exhaust system for the KTM 390 Duke has been meticulously designed and manufactured to exacting standards. Each component is crafted from high-grade Stainless 304 steel, renowned for its exceptional durability, corrosion resistance, and ability to withstand the extreme temperatures generated by high-performance motorcycles. The CNC mandrel bent link pipe ensures smooth, unrestricted exhaust flow throughout the system, eliminating the restrictive pinch points commonly found in crush-bent alternatives.

The mandrel bending process is crucial for maintaining consistent internal diameter throughout all bends in the exhaust system. This precision manufacturing technique allows exhaust gases to flow more efficiently, reducing back pressure and enabling your engine to breathe more freely. The result is noticeable improvements in throttle response, particularly in the mid-range where the single-cylinder engine of the 390 Duke truly comes alive.

Complete Exhaust Kit Contents and Fitment

Every ktm performance superbike exhausts kit arrives complete with everything you need for a straightforward installation. The comprehensive package includes one precision-engineered Stainless 304 CNC mandrel bent link pipe that connects seamlessly to your existing OEM downpipes. This direct-fit design means you won’t need to modify or replace your standard headers, making this an ideal upgrade for riders who want enhanced performance without extensive mechanical work.

Also included in your kit is one stainless steel exhaust strap and one exhaust strap rubber mount. These essential components ensure your new exhaust system is securely mounted to your motorcycle frame, preventing unwanted movement and vibration whilst allowing for the natural thermal expansion that occurs during operation. The rubber mount acts as an isolator, reducing the transmission of vibration to the chassis and maintaining a quiet, rattle-free installation.

Why Choose Our KTM Performance Superbike Exhausts

The KTM 390 Duke is already an impressive machine straight from the factory, but the standard exhaust system is typically designed with strict noise regulations and cost considerations in mind. Our performance exhaust system unleashes the true potential of your Duke’s 373cc single-cylinder engine. Riders consistently report sharper throttle response, improved power delivery throughout the rev range, and a more engaging soundtrack that transforms every journey.

Weight reduction is another significant benefit of upgrading to our exhaust system. Performance motorcycles thrive on reduced mass, and removing unnecessary weight from the rear of the motorcycle improves handling dynamics, acceleration, and overall agility. The KTM 390 Duke’s nimble character becomes even more pronounced with this weight-saving modification.

The enhanced exhaust note deserves special mention. Whilst remaining respectful of noise regulations when ridden sensibly, our exhaust delivers a deeper, more purposeful tone that reflects the sporting nature of your machine. The characteristic thump of the single-cylinder engine becomes more pronounced, creating an addictive soundtrack that makes every ride more enjoyable. You can hear the exhaust in action by viewing our YouTube demonstration video, which showcases the sound quality and volume levels.

Installation and Compatibility

One of the standout features of this exhaust system is its exceptional ease of installation. Designed to fit straight to the standard OEM downpipes without modification, the system can typically be installed in under an hour with basic hand tools. This direct-fit approach means you won’t need specialized equipment or professional assistance, though we always recommend having your work inspected by a qualified mechanic if you’re uncertain about any aspect of the installation.

The exhaust has been specifically engineered for the KTM 390 Duke from 2019 onwards, ensuring perfect compatibility with all model years from this generation. The mounting points align precisely with the factory locations, and the overall dimensions have been carefully calculated to provide adequate ground clearance and avoid contact with bodywork or mechanical components.
