Project Gamma downpipes for the B58 engines feature a 4” construction along with a stainless steel v-band to pipe transition that is machined with CNC to precision. Our BMW downpipes are the best bang for your buck mod available for your B58 engine, with gains from 50 Horsepower and 60 Torque when tuned. Project Gamma keeps the full pipe diameter right up to the turbo instead of necking it down, which helps flow. They're hand-built from 304 stainless steel, which resists rust.
The pipes in the photos have the optional ceramic coating. Add the ceramic coating option to cut heat in the engine bay; without it, the downpipes come polished.
