For headers, only the shorties above are CARB compliant, and from what I've heard shorties in general don't offer any meaningful gains vs stock for an SS. For what it's worth I've heard ARH products are very high quality, and that their shorties are better quality than others.

I was talking with a GM Performance specialist at an event last weekend and he said that the ARH shorties give about 14-16hp gain with no tune required, not substantial, but thats 3.5-4%, better than a kick in the head IMO.
