Is a collector mod worth doing on dc header?
hey guys i have a 01 sh and i was just wondering if its worth doing a collector mod on a dc header and if so does it come close to #'s compared to some high tech headers like SMSP and prospeed and a couple of others?
From my understanding of this topic, doing the mod is better than the oem header but not as much as others such as smsp, greddy, etc
