Show original supplier description
The VRSF B48 Downpipe is engineered to significantly enhance the performance of your BMW's B48 engine. This upgraded downpipe promotes an increase in horsepower, faster turbocharger spool, and a more aggressive exhaust tone. It is meticulously hand-crafted from tig-welded, 304-grade stainless steel, ensuring durability and optimal exhaust gas flow through its smooth, radius-bent design. This downpipe offers a performance gain of 25-30hp when used in conjunction with a tune. It features a brushed finish, with an option for a high-temperature Cerakote coating for added resilience. VRSF backs this product with a lifetime warranty and a "No Hassle" satisfaction guarantee. Important fitment notes: This downpipe is specifically for vehicles equipped with the B48 engine and is intended for non-US market models. US market models require part number 10302046. It will not fit cars equipped with an OPF (Otto Particulate Filter). Right-hand drive (RHD) models may require clearancing or modification to avoid interference with the steering column.
