The Milltek Sport Cat Back Exhaust System is designed for Audi RSQ8 4.0 V8 Bi-Turbo models without the factory OPF/GPF particulate filter. This exhaust solution is for the driver who wants to unleash the full sound of the RSQ8 engine and improve exhaust flow while maintaining the car's daily drivability and premium driving experience.

The Cat Back system replaces the section of the exhaust system after the catalytic converter and adds spaciousness, depth and sportiness to the car's sound without making it annoyingly loud.

Deeper and sportier V8 sound

The Milltek Sport Cat Back is tuned to support the character of the RSQ8 4.0 V8 Bi-Turbo model and offers:

• deeper and richer sound at idle

• more lively and powerful sound in accelerations

• sporty but controlled sound even at high revs

• no annoying resonance or unpleasant drone when driving on the road

The sound profile is designed to highlight the character of the V8 engine in a refined and sporty way.

Improved flow and ride feel

Milltek Cat Back Exhaust System:

• reduces exhaust back pressure after the catalytic converter

• improves engine throttle response and responsiveness

• enhances exhaust gas flow throughout the entire rev range

• also supports executable software updates or other tuning parts

The freer-flowing structure makes the driving experience more dynamic and the engine response sharper.

Direct bolt-on installation

The exhaust system is designed so that it:

• fits directly into the original mounting points

• installed without welding or permanent modifications

• preserves the car's original chassis and drivetrain functionality

OEM-level fit ensures a precise fit and a clean finish .

304L Aircraft Grade Stainless Steel

The entire system is made of high-quality 304L grade stainless steel , which offers:

• excellent corrosion and heat resistance

• long-lasting structure even in intensive use

• flow-optimized internal design

• carefully finished welds

The choice of materials meets the premium quality requirements of Milltek products.
