So after many hours filled with Google research i'm begining to believe that nobody makes headers for the Supercharged 1st gens, Every header that i've come across says "Non-Supercharged Only" somewhere in writing on the page. Please correct me if i'm wrong or tell me where i can find the S/C headers or if the Non-S/C ones will work. Also what size piping should i go with for optimal backpressure? 3"? 2 3/4"? As of now still only boosting the stock 7psi, will be installing my pulley very soon, will be boostin 10-12 psi depending on what size pulley i have. The pulley came with my truck (not installed) when i bought it, also i don't have calipers to measure the size. I attend Tech School for Auto Mechanics so i can do all my work there. Please tell me what you think.
