Overview

The VRSF B48 catless downpipe is an exhaust component designed to increase power, improve turbo spool, and create a more aggressive exhaust note. It is handcrafted from SS304 grade stainless steel and features smooth radius bends to reduce turbulence and enhance flow. This downpipe is compatible with the stock catback and aftermarket exhausts.

Show original supplier description

The VRSF B48 catless downpipe is designed to be a direct replacement for your non-US market BMW, offering significant improvements in power output, turbo spool times, and exhaust sound. Constructed by hand from TIG-welded, 304-grade stainless steel, it features smooth radius bends engineered to minimize turbulence and maximize exhaust flow. Installation of this downpipe is estimated to yield gains of 25-30 horsepower when paired with a tune. It comes with a lifetime warranty and a "No Hassle" satisfaction guarantee from VRSF, ensuring quality and peace of mind. Important fitment notes apply: This downpipe is exclusively for vehicles equipped with the B48 engine. It is intended for international (non-US) market vehicles only; US market vehicles require part number 10302046. Additionally, this downpipe will not fit on cars equipped with an OPF (Otto Particulate Filter). Right-hand drive (RHD) models may require clearancing or modification to accommodate the steering column.
