WELCOME TO THE NO AUDI TAX ZONE
THE NO OVERPAY ZONE.
THE "WHY AM I PAYING $1,000+ FOR EXHAUST PIPES?" ZONE.
THE "IT'S STAINLESS STEEL PIPE — GET REAL" ZONE.
XS-POWER and SSAC have been supplying Audi turbo enthusiasts with performance exhaust hardware for years. Our philosophy is simple: build serious performance parts and sell them at a price that makes sense.
You shouldn't have to spend four figures just to free up the exhaust side of your Audi 2.7T.
These XS-POWER / SSAC Audi 2.7T 3-inch to 2.5-inch high-flow downpipes are designed for enthusiasts looking to reduce exhaust restriction on compatible Audi B5 S4, C5 A6 and C5 Allroad 2.7T twin-turbo applications.
The legendary Audi 2.7T / 2.7L BiTurbo V6 responds extremely well to exhaust-side modifications. The factory exhaust system was designed around OEM requirements for sound, emissions, packaging and comfort. Performance enthusiasts often want something very different: FLOW.
These performance downpipes use a large 3-inch upper section transitioning to a 2.5-inch exhaust connection, providing a high-flow path for exhaust gases leaving the turbochargers.
Reducing unnecessary post-turbine restriction can support:
- Improved exhaust flow
- Reduced exhaust backpressure
- Quicker turbo response
- Improved throttle response
- Support for modified K03 and K04 turbo setups
- A more aggressive 2.7T exhaust note
- Improved breathing for tuned performance applications
3" TO 2.5" HIGH-FLOW DESIGN
Pipe diameter matters on a turbocharged exhaust system. These downpipes begin with a large 3-inch / approximately 76MM section to provide additional exhaust volume immediately downstream of the turbocharger.
The system then transitions to approximately 2.5 inches / 63.5MM for compatibility with the intended downstream exhaust configuration.
This combination gives Audi 2.7T enthusiasts the large-volume flow characteristics they want near the turbo while maintaining a practical connection to a compatible exhaust system.
BUILT FOR K03 & K04 AUDI 2.7T PERFORMANCE
Whether you're maintaining a modified K03 2.7T or building a K04-equipped Audi S4 2.7T, improving the exhaust path after the turbochargers is an important part of a properly planned performance combination.
These XS-POWER / SSAC downpipes are designed around compatible Audi 2.7T K03 and K04 turbo applications.
That makes them an excellent consideration for enthusiasts searching for:
- Audi S4 B5 K03 downpipes
- Audi S4 B5 K04 downpipes
- Audi 2.7T 3 inch downpipes
- B5 S4 performance downpipes
- Audi A6 C5 2.7T downpipes
- Audi Allroad 2.7T downpipes
- 2.7T twin turbo exhaust upgrades
- Audi 2.7 BiTurbo performance exhaust
- 3" to 2.5" Audi downpipes
- Stainless steel B5 S4 downpipes
AND YES — THEY SOUND AWESOME
One of the best parts of opening up an Audi 2.7T exhaust system is hearing more of what made this engine famous.
Expect a more aggressive performance character with deeper exhaust tone, more noticeable turbo spool and considerably more 2.7T personality, depending on the remainder of your exhaust system.
Search YouTube for modified B5 S4 2.7T K03 and K04 exhaust systems and you'll understand why these cars continue to have such a dedicated enthusiast following.

PERFORMANCE WITHOUT THE "AUDI TAX"
Let's make this simple.
Stainless steel is stainless steel.
A bend is a bend.
A weld is a weld.
Flow is flow.
We're enthusiasts too, and we don't believe a performance part suddenly needs an outrageous price tag just because it bolts onto an Audi.
XS-POWER / SSAC = SERIOUS PERFORMANCE WITHOUT THE RIDICULOUS MARKUP.
Spend the money you save on something else your B5 actually needs. Turbos. Fuel. Tuning. Intercoolers. Tires. Or maybe just more boost.
