The CTS Turbo high-flow exhaust pipe for the Audi A4 B5 1.8T is designed as a direct replacement for the standard catalytic converter installed directly after the turbocharger.
It is made from 3″ T304 stainless steel, with smooth mandrel-bent pipes and hand TIG-welded joints. The expansion at the beginning measures almost 4″ before narrowing to 3″, allowing the best possible exhaust gas flow during the transition from the turbocharger to the pipe. The product improves exhaust flow, can contribute to increased power and produces a fuller, sportier sound.
