200-Cell High-Flow Catted Downpipe

The VRSF 10302011 is a performance high-flow catted downpipe upgrade for N55 engines, designed to significantly reduce back-pressure by replacing the factory catalytic converter. Crafted from hand-welded SS304 grade stainless steel with smooth, mandrel-bent transitions, this downpipe promotes increased exhaust flow, resulting in faster turbo spool, noticeable power gains, and a more aggressive exhaust note. The unit features a 200-cell high-flow race cat and CNC-machined SS304 stainless steel flanges for a secure fit. This downpipe is engineered to provide performance enhancements, with manufacturer claims of 20-25hp gains when paired with a tune. VRSF backs this product with a Lifetime Warranty. It is recommended that a DME tune accompany the installation to prevent potential check engine lights. This part fits various BMW models including the F22 M235i/M235i xDrive, F30 335i/335i xDrive, F32 435i/435i xDrive, F33 435i/435i xDrive, and F87 M2, all equipped with the N55 3.0L engine. Production dates after 08/13 may have specific fitment considerations, and users are advised to use the vehicle selector to confirm compatibility. It is important to note that this product is not for sale or use in California on any pollution-controlled vehicle, as per California Air Resources Board regulations.
