Why Upgrade Your Factory Downpipe?
The factory M133 downpipe is a major bottleneck once you increase boost. This 3.0” catless downpipe dramatically reduces backpressure, allowing your turbo to spool faster and breathe more freely — delivering quicker response, stronger mid-range power, and a much more aggressive exhaust note.
Tuning is highly recommended to unlock full performance and prevent check engine lights.
