2007 WRX STI Cobb Stage2 - Gruppe-S Equal Length Headers 1
Decided to get some el headers to see if I could get the STI to spool even earlier. I had PDXTuning make a new map. So far seems like mid/upper range is better. The header is not wrapped yet, so I’ll probably give my thoughts on low end torque afterwards.
