XS-POWER Audi B5 S4 2.7T Version III Straight Midpipes

Non-Resonated • Non-Catted • V-Band • 321 Stainless Steel • High-Flow Exhaust Upgrade

XS-POWER PERFORMANCE PRESENTS: the Version III high-flow straight midpipe set engineered for the legendary Audi B5 S4 2.7L Twin Turbo platform.

Designed for performance-oriented Audi 2.7T exhaust systems, these non-resonated, non-catted straight midpipes eliminate the restriction and complexity of resonators and catalytic converters while providing a clean connection between compatible V-band downpipes and the downstream exhaust system.

Built from premium 321 stainless steel and equipped with V-band connections, the XS-POWER Version III midpipes are designed for high-temperature turbocharged applications where exhaust flow, durability and serviceability matter.

VERSION III PERFORMANCE DESIGN

The Audi 2.7T platform responds extremely well to improvements in exhaust flow. Restrictive exhaust components can increase backpressure downstream of the turbochargers, while a properly configured high-flow exhaust system allows exhaust gases to exit more efficiently.

These Version III straight midpipes provide a simple, performance-focused exhaust path with no catalytic converters and no resonators.

• ✔ Version III upgraded design
• ✔ Non-resonated straight-through configuration
• ✔ Non-catted / catalyst-free design
• ✔ Premium 321 stainless steel construction
• ✔ V-band connections
• ✔ High-flow exhaust path
• ✔ Reduced exhaust restriction compared with restrictive midpipe configurations
• ✔ Aggressive performance exhaust sound
• ✔ Designed for modified Audi B5 S4 2.7T applications

⚙️ PREMIUM 321 STAINLESS STEEL CONSTRUCTION

These are not ordinary mild-steel exhaust pipes.

XS-POWER uses 321 stainless steel for this Version III application. 321 stainless is particularly well suited for high-temperature exhaust environments and is an excellent material choice for performance turbo exhaust components.

For a twin-turbo Audi where exhaust components routinely experience repeated heating and cooling cycles, material quality matters.

• ✔ Excellent high-temperature capability
• ✔ Excellent corrosion resistance
• ✔ Designed for demanding turbocharged exhaust environments
• ✔ Premium performance construction
• ✔ Built for long-term performance use

NON-RESONATED STRAIGHT-PIPE CONFIGURATION

Want the aggressive sound of the Audi 2.7T without a resonator reducing exhaust volume?

This is the setup.

The non-resonated design provides a more direct exhaust path and a substantially more aggressive exhaust character than a resonated midpipe configuration.

PLEASE NOTE: Non-resonated exhaust components are intentionally louder than resonated systems. Exhaust volume and tone will vary depending on downpipes, catback exhaust, turbochargers, engine modifications and tuning.

NON-CATTED HIGH-FLOW DESIGN

These are straight, non-catted midpipes.

There are no catalytic converters incorporated into these pipes, creating a straightforward exhaust path for performance and competition applications.

This configuration is particularly attractive for modified B5 S4 builds using upgraded turbochargers, high-flow downpipes and performance catback exhaust systems.

V-BAND CONNECTION SYSTEM

V-band exhaust connections provide a clean and serviceable connection for compatible performance exhaust components.

• ✔ Quick assembly and removal
• ✔ Excellent alignment
• ✔ Compact connection design
• ✔ Ideal for performance exhaust applications
• ✔ Cleaner installation than many traditional multi-bolt exhaust flanges
