Audi TTRS MK3 Electronic Cat-Back Corsatronic

Welcome to the world of five-cylinder fury

The RS3 and TTRS, from the moment they leave the factory, have high performance and clear power
But the rear exhaust system (Catback) kills much of the character that the car deserves
And this is where the course-tronic comes in

We raised the system size to 3 inches to provide greater exhaust flow and a stronger, cleaner sound
And the real magic starts from the rear Y section

When the valves are open, the exhaust flows directly from the large outlets without any obstructions
But when closed, the exhaust passes through a four-chamber muffler to significantly reduce sound
The result? The exhaust system you dreamed of for five-cylinder Mk3 cars is now a reality

The system is compatible with
Audi TTRS 8V from model year 2017 to 2023

System specifications
Made of T304 stainless steel
Precise TIG welding for high durability
Fully bent with Mandrel-Bent technology for maximum flow
Electronic valves with the same system as the factory and support the use of original Audi valves
Lighter than the factory system by 14.8 pounds
Distinct outlets that match the TTRS rear design
Reversible to the original system at any time
