BD's Screamer line of turbos offer drop-in, stock-appearing units that add an additional punch in power without major modifications to intake or exhaust systems. The L5P Screamer for 2017-up Duramax engines feature custom compressor and turbine wheels that have been designed to give you increased airflow without compromising on low end performance. Manufactured using OEM housings, the L5P Screamer turbo is machined to accept the new larger 66.2mm compressor and 67mm turbine wheels which will allow for better airflow (up to 80 lb/min) and lower exhaust gas temperatures. With supporting modifications, the L5P Screamer can achieve up to 680hp.
