The Neuspeed 48.02.47 Hi-Flow Turbo Discharge Conversion kit removes serious flow restriction from the discharge side of the turbocharger for better response with less turbo lag and increased HP. The Neuspeed kit is the most complete kit on the market for improving flow on the discharge side of the turbocharger, offering full flow from the turbo outlet all the way to the intercooler hose. The Neuspeed Hi-Flow Turbo Discharge Conversion Kit includes a machined billet aluminum discharge adapter that reduces restriction with its full size smooth bore exit for better flow to transition out of the turbo and then into the Neuspeed 2.5" (63.5mm) ID silicone hose. The next and most important item in the kit is Neuspeeds one piece mandrel bent aluminum discharge pipe with a full 2.5" (63.5mm) diameter. The discharge pipe uses the factory rubber mounts with rolled lips on both ends to make a more secure connection to the silicone hose with the included "T" bolt hose clamps. The Neuspeed components are capable of 65% more airflow than the OEM components.
