Vorsprung Autowerk TruTone UltraFlow Downpipes, Audi 3.0T V6 Supercharged

Audi B8/B8.5 & C7/C7.5 3.0T High-Flow Resonated Downpipes

Upgrade your Audi B8/B8.5 S4/S5 or C7/C7.5 A6/A7 3.0T with high-flow resonated downpipes engineered for increased performance, improved exhaust flow, and an aggressive exhaust note without the unwanted drone.

Unlike typical aftermarket Audi 3.0T downpipes, our system uses dual front resonators or high-flow catalysts feeding into our proven dual straight-through resonator. This three-resonator design is engineered specifically for enthusiasts who want to run a high-flow exhaust setup without catalytic converters in the factory downpipe location while maintaining a refined, comfortable sound inside the cabin.

For catless test pipe and header setups, controlling volume, rasp, and drone becomes even more important. These downpipes are designed to be the ultimate exhaust solution for catless and header-equipped Audi 3.0T builds, taming the harsh frequencies commonly associated with unrestricted exhaust setups without sacrificing the aggressive character you're looking for.

The result is a freer-flowing exhaust system with a deeper, more refined tone under throttle while keeping highway cruising comfortable—even on highly modified exhaust configurations.

Key Benefits

• Ideal for catless and header setups where additional sound control is critical
• Increased horsepower and torque potential through improved exhaust flow
• Improved throttle response for a more responsive 3.0T
• Smooth, unrestricted exhaust flow
• Deep, aggressive exhaust note under acceleration
• Engineered to minimize drone and harsh exhaust frequencies
• Helps control rasp associated with catless 3.0T exhaust systems
• Direct bolt-on fitment for a straightforward installation
• Designed specifically for the Audi 3.0T platform

The Ultimate Solution for Catless & Header 3.0T Builds

Removing the factory catalytic converters—or stepping up to a full header setup—can unlock performance and dramatically increase exhaust volume, but it can also introduce rasp, harshness, and persistent cabin drone.

Our multi-resonator downpipe design was developed to address exactly that problem.

By combining dual drone-reducing front resonators with a dual straight-through main resonator, the system targets undesirable frequencies while maintaining the flow characteristics demanded by high-performance builds. This makes it an excellent match for catless test pipes, high-flow catalyst setups, and aftermarket headers.

If you're building a high-output Audi 3.0T and want the benefits and aggressive sound of an unrestricted exhaust without making the car unpleasant to drive, these downpipes are designed to provide the balance you've been looking for.

Premium Construction & Engineering

High-Temperature Resonator Packing
Our resonators use specially sourced packing material rated to 1,000°C, significantly exceeding the temperature capability of conventional E-glass materials commonly used in exhaust systems. This helps prevent premature packing burnout in high-temperature performance applications.

Three-Resonator Drone-Reduction Design
Dual front resonators feed into a dual straight-through resonator to control unwanted frequencies without unnecessarily restricting exhaust flow.

Optional High-Flow Catalysts
Available with high-flow catalytic converters featuring a high-PGM washcoat to help reduce exhaust odor while maintaining strong flow characteristics.

3D-Scanned Fitment
Designed using precise 3D vehicle scans for accurate alignment and OEM-like fitment.

Heavy-Duty Flex Pipes
Extra-durable flex sections are engineered to withstand the movement, vibration, and heat associated with high-performance Audi 3.0T applications.

Solid-Welded Resonator End Caps
Our resonator end caps are fully welded for improved durability and resistance to repeated exhaust pressure pulses.

Laser-Perforated Resonator Tubing
Precision laser-perforated internal tubing helps prevent cracking and deterioration inside the resonator for dependable long-term performance.

Designed for the Audi 3.0T Platform

These resonated downpipes are engineered for compatible Audi B8/B8.5 and C7/C7.5 3.0T models, making them an ideal upgrade for enthusiasts looking for improved exhaust flow and a more exciting supercharged 3.0T exhaust note without sacrificing everyday drivability.

Whether you're running factory manifolds, catless test pipes, high-flow cats, or aftermarket headers, these downpipes are designed to deliver the combination that matters: performance, sound control, fitment, and durability.
