yesterday I bought a set of Ebay headers for my 325xi touring. I still need to get new studs and ceramic spray. Ive done A TON of research on header installs but I havent found much on installing headers on an XI car. The xi's have extra bracing and other "junk" up front for the front wheel drive. worst case ill have to take the engine off its mounts. Does anyone know anything about installing headers on an xi?!?!?!
