APR Exhaust Systems Include:
- 2.5" Downpipe
- Full Cat Back Exhaust
- Muffler with Rolled, Round Tips
- Install Hardware
APR's A4 Exhaust is a stainless steel, 2.5" mandrel bent, cat-back exhaust. On an A4, the catalytic converter is bolted to the turbocharger and then the exhaust begins with the downpipe. Unlike most other aftermarket exhausts, the APR exhaust includes a downpipe. This exhaust is very quiet and simply changes the tone of the exhaust to a deep, unobtrusive sound. With TIG welding, fully stainless construction, and CNC'ed hangers, you will not find a higher quality system on the market.

APR is proud to be the Authorized Distributor for Carbonio Cold Air Intake (CAI) systems. Manufactured from aerospace grade carbon fiber, Carbonio further improves this material by incorporating a proprietary thermal barrier layer in its construction. The result is an exceptionally light and strong part that minimizes intake temperatures. This ensures that the engine optimizes power by receiving the coldest and most oxygen rich air possible.
Benefits of the Carbonio CAI System include:
- Increases Horsepower and Torque
- Improves Throttle Response
- Decreases Turbo 'Lag'
- Flattens Torque Curve (engine is less 'peaky')
- Improves Fuel Economy
- Enhances Engine's Volumetric Efficiency
- Enhances Sound of Turbo Diverter Valve
- Works with All Aftermarket Diverter Valves
- Installs in an Hour (does not require bumper or headlight removal)
- Maintains All Factory Emissions Components
- Fits Both Manual and Automatic Transmissions
- Unique Thermal Barrier Composite Construction Ensures Low Inlet Temperatures
- Fully Compatible and Complimentary with APR Software and Exhaust systems
APR Turbo Compressor Inlet Hose for 97-01 Audi A4 1.8T
APR is proud to release our newest addition to the APR Motorsport lineup, APR Compressor Inlet Hoses for the 1.8T. We designed these hoses to fill a gap in the market where other silicone hoses simply don't perform.
After extensive testing our engineers have found that the OEM compressor inlet hose is not rigid enough to prevent collapse during high boost situations where airflow to the turbo is most important. A collapsed hose creates a huge airflow restriction that robs your motor of potential power!
