<br> The most restrictive part of any exhaust system is the catalytic converter. The stock catalytic converter is meant to filter the flow of exhaust gases to reduce the amount of harmful gases into the atmosphere. Because of this, lots of potential performance is By piped eliminate the stock catalytic converter and reduce exhaust backpressure. By maximizing exhaust flow, this downpipe allows the turbo to spool up and build boost quicker. The result brings out the vehicle's performan Eg potential by giving it a free high flowing exhaust system.<br><br>Specification:<li>Made of High Quality T-304 Stainless Steel with Computerized Mandrel-Bends</li><li>Inlet/Outlet Size: 2.50"/ 3.00"</li><li>Piping Diameter: 3.00"</li><li>TIG Welded CNC Machine Mandrel-Bent Tubing</li><li>2 X O2 Sensor Bung Insertion and Metal Gasket Included<br><br>Package Included:</li><li>1 X Set of Downpipe Kit </li><li>Hardware as Shown in the Picture Above<br><br>Fitment:</li><li>97-05 Audi A4 (B5/ B6) Typ 8D/ Typ 8E/ 8H</li><li>98-05 Volkswagen Passat (B5/ B5.5) Typ 3B/ 3BG</li><li>Fits Models with 1.8L/1.8T l4 DOHC Turbocharged Engines ONLY</li>
