{"product_id":"ss304-stainless-steel-downpipe-upgrade","title":"SS304 Stainless Steel Downpipe Upgrade","description":"The VRSF Downpipe Upgrade is engineered to significantly enhance the performance of your N55 BMW engine by eliminating the restrictive factory catalytic converter. This modification reduces back pressure, resulting in quicker turbo spool, a noticeable increase in horsepower and torque, and a more aggressive exhaust tone. The downpipe is meticulously hand-crafted from mandrel-bent SS304 grade stainless steel, featuring CNC-machined flanges for precise fitment.\n\nConstructed with smooth radius bends to minimize turbulence and maximize flow, this downpipe is available with an optional 200-cell high-flow catalytic converter. VRSF offers this downpipe with a lifetime warranty, underscoring their commitment to quality and durability.\n\nIt's important to note specific fitment requirements based on vehicle production date. M135i and 335i models produced up to July 2013 require the 3.5\" version, while those produced after July 2013, along with all M235i and 435i models, require the 4\" version. Confirmation can be made by checking the turbo wastegate location. Professional installation is recommended, and fitment questions should be directed to the retailer. VRSF warrants the downpipes for a lifetime, but the ceramic coating and catted versions carry a 1-year warranty.","brand":"VRSF","offers":[{"title":"Default Title","offer_id":52664101372216,"sku":"10302010","price":269.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687538477.jpg?v=1784333256","url":"https:\/\/store.motormia.co\/products\/ss304-stainless-steel-downpipe-upgrade","provider":"MOTORMIA","version":"1.0","type":"link"}
