Full T304 Stainless Steel System with Electronic Valve Control
Overview
The Audi B9 RS5’s 2.9L twin-turbo V6 is a powerhouse—but the factory exhaust hides much of its true character behind heavy, restrictive components. The Valvetronic Designs Full Valved Exhaust System unleashes the car’s full vocal potential, delivering an aggressive, motorsport-inspired tone when desired, and quiet refinement when needed.
Unlike typical aftermarket setups requiring multiple parts from different vendors, our system is a complete, single-package solution—from the OEM or aftermarket downpipes all the way to the exhaust tips. No more combining a cat-back from one brand with resonator sections from another—this is a true one-stop upgrade.
With the valves open, the RS5 gains a sharper tone, aggressive overrun crackles, and a commanding presence. Close the valves, and the car returns to near-stock quietness, making it ideal for both spirited driving and daily use.

Exhaust came undamaged but was
"Exhaust came undamaged but was missing the valve controller and remote. There were no install directions in the box and there are none online. I had to install the system without the valve controller and remote. I feel instructions would be helpful as to the clamps. The system sounds great and is high quality. The items were package and wrapped well. I don’t want to give a bad review things happen hoping to receive the valve controller and remote in a timely fashion."

"This is a very fun exhaust! Nice throaty sound with the ability to turn it down when needed. Keeping the vehicles classy and luxurious feel. However; what’s best is Valveteonic’s customer service. They respond so quickly!!! And they also take a great deal packing your exhaust. Highly recommend!"

Q&A
Hi. 2024 audi rs5 model, it has OPF in the mid pipe. Do you have the module in the exhaust system to help in deleting the OPF and no check engine light comes.
As EU and American cars come with different exhaust configurations, we recommend purchasing the OPF delete modules separately as they are not included in the kit
