Full Custom Exhaust Systems

Handcrafted performance, built for sound, style, and precision.

Fully Bespoke Design

Every system is built to your exact specifications for the ideal sound and performance.

Performance Gain

Improved airflow and reduced back pressure for better power and efficiency.

Custom Sound Profiles

From subtle enhancement to full race tone, tailored to your preference.

Built with precision and purpose.

Designed to boost performance while keeping your setup perfectly balanced.

At Midnight Developments, we offer a range of decat and sports cat upgrades designed to improve exhaust flow, boost power, and enhance sound. Whether you’re chasing maximum performance for the track or a refined, road-legal setup, we can tailor the perfect solution for your vehicle.

A decat system removes the restrictive catalytic converter, resulting in faster turbo spool, improved throttle response, and increased power — ideal for off-road or motorsport applications. For drivers who need to remain emissions-compliant, our high-flow sports cat systems offer a similar performance gain while keeping your car road-legal and MOT-ready.
