IRL B58 Gen 3 Downpipe
Wake up your engine and clear the back pressure with the IRL B58 Gen 3 downpipe. By replacing your stock catalytic converters, it lets the turbos spool faster and reach maximum power — a tuned B58 on stock turbos can expect a solid 30 HP increase. A built-in flex pipe section reduces stress and vibration for a smoother ride.
Features
- Smooth bends for maximum airflow with no drone
- Up to 30 HP increase on the stock turbos
- Built-in flex pipe section to cut stress and vibration
Professional installation recommended.
