Catless downpipe for 9th gen si. Had to get the pipe welded with a new flex pipe. It will fit on your 9th gen ONLY if you have a catback for our platform.
The elbow you see on the side is a defouler for the O2 sensor. It tricks the computer into thinking there’s cats and will help you pass inspection. I have gaskets.
Made 213 whp and 177 tq with this pipe and setup I had. If you’re on a budget for a downpipe this will get the job done for you.
