Exhausts

The B58 turbo breathes through the factory catalytic converter, the biggest bottleneck of the entire exhaust. This 4.5″ stainless steel downpipe removes it: 135 mm V-band at the turbo, 3″ at the exhaust, two connections for lambda sensors. Base for Stage 2 on the M140i, M240i, 340i and 440i.
