VRSF BMW B48 Catless Downpipe

This high-flow downpipe is the best bang-for-buck modification available for the B48. By eliminating the restrictive catalytic converter in the factory downpipe, backpressure is significantly reduced, resulting in faster turbo spool, a genuine increase in power (25-30hp with a tune), and a more aggressive exhaust note.

Hand-crafted from TIG-welded 304-grade stainless steel with smooth radius bends to decrease turbulence, this downpipe fits the stock catback as well as all aftermarket exhausts.

Important fitment notes:

• This downpipe will not fit vehicles equipped with an OPF (Otto Particulate Filter), common on later emissions-compliant markets.
• This is an international-market part only. US-market vehicles require a different part number.
• RHD models require clearancing/modification to clear the steering column, this is not a straightforward drop-in for RHD cars.
