The Buddy Club Racing spec Honda 9th Gen Civic Si 3" All-Motor Downpipe is available now! Designed to extract maximum power from naturally aspirated K24Z7 engines, our high flowing design delivers significant power and torque gains throughout the power band by reducing back pressure and increasing flow. This Downpipe also pairs well with the stock exhaust and the Skunk2 and Full Race catback systems.
- 100% 304 stainless steel construction
- Mandrel bent, large radius bends
- Precision TIG welded and purged
- CNC machined stainless steel oxygen sensor bungs
We also strongly recommend the Hasport rear mount as the stock Honda mounts can cause severe engine movement.
