Ferrita Downpipe Audi S4 (B9) 3.0 TFSi

For numerous turbocharged cars a BSR 3" downpipe with sports catalyst is available giving further power benefits through access to broader and higher boost pressures. As with BSR's Sportflow cat back exhaust systems, our downpipes and high flow catalytic converters meet our exacting standards for performance and durability. BSR downpipes should be combined with a BSR Sportflow system and BSR Stage 3 software.
