This 4" downpipe for the Mercedes-Benz C300 (M274) features a CNC-machined stainless steel V-band-to-pipe transition. Rather than necking down near the turbo, it keeps a full 3D design for greater flow, with gains of around 50 HP and 60 lb-ft when tuned. Handcrafted from corrosion-resistant 304 stainless steel.
