This 3.5″ turbocharger downpipe, often referred to as the turbo direct pipe, is designed to remove the Diesel Oxidation Catalyst (DOC) and enhance exhaust flow from the turbo, thereby boosting engine performance. Unlike other versions that start from behind the DOC and are suitable for emissions-on configurations, this model completely eliminates the DOC to maximize airflow and power.
Note that while DPF pipes and full exhaust systems do not incorporate a DOC delete, this pipe is essential for a full emissions removal, though not mandatory for a tune.
