Hey fellas. New to the forum and the supercharged world. 02 Grand prix 40th ann with 0 mods. Tried clicking on links to get answers but says not found. Anyways, going to order headers, seems SD is the way to go. Any places in Los Angeles that works on these. I can do basic installs but sounds like things don't line up for the headers and bending dipsticks may get me frustrated! lol After that looking to do a Cam (love the sound) and change pulley. This common and ok to do without messing with reliability
