Show original supplier description
The VRSF Racing downpipe is a performance-enhancing exhaust component for B48 engine-equipped BMWs. Constructed by hand from tig-welded, SS304 grade stainless steel, this downpipe features smooth radius bends to minimize turbulence and maximize exhaust flow. It comes with a lifetime warranty from VRSF Racing, underscoring the manufacturer's confidence in its durability and performance. It is critical to note that this specific downpipe is intended **only for non-US market vehicles** and will **not fit US models**, which require part number 10302046. Additionally, this downpipe is **not compatible with vehicles equipped with an OPF (Otto Particulate Filter)**. RHD models may require clearancing or modification to accommodate the steering column. A tune is recommended to achieve the advertised gains of 25-30hp.
