Audi B9 S4 / S5 Cat Back CorsaTronic Electronic

Exhaust CourseTronic for the Audi S4 / S5 B9 – the complete solution for a sound like no other!

The EA839 V6 3.0-liter engine on the B9 platform has great capabilities, but the factory sound remains muted and heavy… this is where Kourstronic comes in!
Our complete electronic system connects the exhaust from the downpipe (original or modified) to the final tips, all in one integrated system without the need to gather parts from different places.

All the sound… in one system!

Usually, the market is full of systems that require you to buy a cat-back from one place, and the resonator from another… with Kourstronic, everything is ready in one system designed to give you the best sound and strongest performance.

• Electronic valves with remote: Aggressive and exciting sound when you open the valves, with cuts and real music in every shift

• Closed valves: the car returns quiet as if it were brand new

• Without any annoying drone or frequency inside the car if you were on the original downpipe

Experience stronger than previous generations!

If you switched to the B9 from an older S4 (B6/B7) with a 4.2 V8 engine, you will definitely feel the car's sound is lacking… with Kourstronic, it feels like you returned to the days of strong natural sound, you will relive the enjoyment with every drive.

Features:

• Made entirely of T304 stainless steel

• Electronic valves with remote

• Lighter than the original system by approximately 7.4 kg

• Mandrel bends for better flow

• Professional TIG welding

• You can revert to the original system at any time without issues

Fits:

• Audi S4 models 2017 - 2024

• Audi S5 models 2018 - 2024

No compromises in sound experience… with Kourstronic, everything is in one system!
