The Axion Industries 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.
We also strongly recommend the Hasport rear mount as the stock Honda mounts can cause severe engine movement.

Overall it's a nice product, excellent fitment, only problem I had was trying to reach the second O2 sensor plug it didn't reach so I had to take it off the clip so that it could reach.

It looks excellent from the outside but the welds at the inlet leave something to be desired. I had to use a sandpaper cylindrical screw gun attachment to deburr the welds and take off the lip edge on the bottom. If I had to buy another DP, I would buy a Full Race unit.
