G8X M2 | M3 | M4 - S58 Downpipes - Premium Auto Styling
Upgrade to LAB Downpipes and remove the factory backpressure created by your stock catalytic converters. With improved exhaust flow, your S58 turbos can spool faster and reach their power potential—especially when paired with a proper tune.
On a tuned S58 with stock turbos, LAB Downpipes have shown gains of up to 30 HP.
The integrated flex pipe section helps reduce stress on the exhaust system while minimizing unwanted vibration for a more reliable, refined setup.
