VCTR Performance BMW B46/B48 G/F-Chassis Downpipe

Overview

The factory BMW 120i/220i/230i/320i downpipe carries a restrictive catalytic converter section that chokes exhaust flow right where the turbo needs it least. This downpipe opens that bottleneck up, improving flow from the turbo back and unlocking the top end of the power curve.

Why Upgrade?

• Improved exhaust flow from the turbo outlet back
• Reduced backpressure for better spool and top-end power
• construction for long-term durability
• Direct OEM-location installation

Built for the Drive, Not Just the Dyno

A downpipe is one of the highest-return changes you can make on a turbocharged platform — the factory unit is designed around noise and emissions compliance first, flow second. This one puts flow first without asking you to compromise reliability.
