Audi MK4 RS3 Cat Back CorsaTronic Electronic

The sound that befits the RS3

The Audi RS3 model 8Y is the pinnacle of performance in the compact sports car category
All-wheel drive, five cylinders, turbo, and torque that exceeds its size by leaps
But no matter how strong the performance is, the experience is incomplete without an exhaust system that matches the spirit and aggression of the car
And this is where the course-tronic comes in

We designed an exhaust system that changes everything
Not only does it give you better sound, but it transforms the entire driving experience
Made from Grade 5 titanium used in aviation
The system is dedicated to those who seek sound, performance, and unmatched excellence

A system designed for detail lovers

The legendary 2.5-liter TFSI engine deserves an exhaust that unleashes its full power
Independent electronic valves from the dealership systems
This means you control the sound, not the modes

Open valves:
A crazy five-cylinder sound, without any restrictions
The exhaust exits from the oval RS-style outlets
An aggressive, sporty sound that raises the hair on your body with every shift

Closed valves:
A smooth and balanced sound for long drives or morning starts
It passes through an internal resonator that gives you a refined tone without drone or disturbance
But it still has that distinctive Audi sound

Why titanium?

Because it's lighter, stronger, and more heat-resistant than stainless steel
Helps reduce weight, improve throttle response, and increase the power-to-weight ratio
This means your car becomes lighter, faster, and more precise in handling
Moreover, the titanium sound has a sharp, metallic tone that sets you apart from everyone
From cold starts to high revs, the sound makes you addicted to driving

Designed for the strongest RS3 in the world

The RS3 modification community is breaking records with horsepower
Our system ensures that the sound matches the performance
Whether you're shooting the quarter mile, taking corners, or cruising on the autobahn
Koursatronic exhaust makes your RS3 impossible to go unnoticed

This is not just an exhaust system
This is a complete experience
Every shift, every acceleration, every brake… tells a story of power, details, and precision
