3" Downpipe Exhaust System with High Flow Catalytic Converter and RSC Resonator

I bought used with only 3000 miles of use but decided not to install.

$600 PLUS SHIPPING

from the APR website:

"APR's 3 inch downpipe with high flow catalyst for the A4 2.0 TFSI is the first true downpipe for the A4 and the only one that incorporates traditional exhaust performance tuning for the new 2.0 TFSI engine. Other 2.0 TFSI engine applications outside of the A4 chassis have historically enjoyed the following benefits that have never before been made available to A4 owners:

3 inch Exhaust Tubing Diameter beginning at the Turbocharger Exit for Maximum Turbocharger Spool and Peak Horsepower
Relocation of the Catalyst to Reduce Backpressure and Turbulent Airflow at the Turbocharger
Incorporation of a 200 Cell Count Catalyst to aid in Turbocharger Spool and Remove Restriction
Considerable Increases in Peak Horsepower, Peak Torque and Fuel Economy"
