decided to get JDL UEL headers for a little extra volume and boxer rumble gurgle.
Power difference isn't noticeable.
The header bolts on JDL headers are 17mm instead of 14mm, and the O2 Sensor kinda blocks the overpipe bolt/nut so I had to put the O2 sensor on after tightening the bolts. It was a bit odd but manageable.
JDL headers are some quality shit though, they look amazing.
