I'm pretty much a newbie to performance modifications. Can anyone please tell me the difference between 4 into 1 Headers and Tri-Y Headers? I know Stillen's G20 headers (Part #508520) are 4 into 1, and HotShot's G20 headers (Part #NS3001), which is what I have, are Tri-Y. What is the difference in HP gain, if any?
