Compact and Efficient Diesel Performance

The Toyota Yaris 1.4 D4D is a small, efficient diesel hatchback powered by a 1.4 litre turbo diesel engine producing 90 PS and 190 Nm of torque through a 5 speed manual gearbox. While it is known for reliability and excellent fuel economy, this visit focused on transforming the driving experience with a custom Toyota Yaris Exhaust designed to deliver a much stronger and more noticeable sound.

Technical Specs and What Sets It Apart

With 90 PS on tap and solid low end torque, the 1.4 D4D engine is well suited to daily driving. However, diesel models are often quieter and more restrained from the factory. To resolve this, a bespoke Toyota Yaris Exhaust System was developed to significantly enhance the sound profile, giving the vehicle a deeper, louder and more purposeful tone while retaining its everyday usability.

Everyday Usability and Market Appeal

The Yaris 1.4 D4D remains a practical and economical choice for city and suburban use. With the upgraded exhaust system in place, the vehicle now delivers a far more engaging driving experience. The improved exhaust note adds character and presence without compromising comfort, making it ideal for drivers wanting more sound from a diesel platform.

Boosted Performance with DKU Custom Exhausts

A custom stainless steel exhaust system was built and fitted to increase overall sound output and improve exhaust flow. The DKU Performance solution reduces restriction and allows the engine to breathe more freely, resulting in improved throttle response and a noticeably louder, more aggressive tone. The finished setup delivers a refined balance between daily drivability and a bold, enhanced exhaust note.
