3" Cast Race Downpipes SS304 Stainless Steel

The VRSF 3″ Cast Race Downpipes are engineered to enhance performance for the 2015-2019 BMW M3, M4, and M2 Competition equipped with the S55 engine. By eliminating the restrictive factory catalytic converters, these downpipes significantly reduce exhaust back pressure, leading to quicker turbocharger spool, a noticeable increase in horsepower and torque, and a more aggressive exhaust sound. Crafted from hand-made, mandrel-bent, tig-welded 3" SS304 stainless steel, these downpipes feature a CAD/CAM designed cast flange for a seamless transition from the turbocharger to the pipe. The smooth radius bends are optimized to decrease turbulence and promote increased flow. Installation hardware, including Grade 12 mounting hardware, is included with purchase. VRSF offers a lifetime warranty against defects and fitment for these downpipes. This product adds an estimated 20-25 HP and 25-30 lb-ft of torque to the wheels when used with a tune. Optional Cerakote High Temperature Ceramic Coating is available, designed to withstand temperatures up to 1800F. Note that the warranty for the ceramic coating is 1 year due to the product's nature. Fitment applies to the 2015-2018 F80/F82/F83 BMW M3 & M4 and the 2018+ F82 BMW M2 Competition (S55 Only).
