{"product_id":"3-inch-cast-stainless-steel-downpipes","title":"3-Inch Cast Stainless Steel Downpipes","description":"The VRSF Racing Downpipes are a direct-fit upgrade for the S55 engine found in 2015-2019 BMW M3 (F80), M4 (F82\/F83), and M2 Competition (F87) models. These 3-inch high-flow downpipes are engineered to replace the restrictive factory catalytic converters, significantly reducing back pressure. This modification results in improved turbo spool times, a notable increase in horsepower and torque (estimated 20-25 HP and 25-30 TQ when tuned), and a more aggressive exhaust sound.\n\nConstructed from hand-crafted, mandrel-bent SS304 stainless steel, these downpipes feature a unique cast stainless steel v-band to pipe transition and smooth radius bends to maximize flow and minimize turbulence. Grade 12 installation hardware is included with purchase.\n\nVRSF also offers optional ceramic coating services utilizing Cerakote's High Temperature Ceramic coating, which can withstand temperatures up to 1800°F. While the downpipes themselves come with a lifetime warranty against defects and fitment, the ceramic coating is covered for one year due to the product's nature. The available surface finishes include Heat Shield, Brushed Finish, and Cerakote High Temp Coating.","brand":"VRSF","offers":[{"title":"Default Title","offer_id":52664053629240,"sku":"10802010","price":479.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687394934.webp?v=1784332523","url":"https:\/\/store.motormia.co\/products\/3-inch-cast-stainless-steel-downpipes","provider":"MOTORMIA","version":"1.0","type":"link"}
