well i have a 05 srt-4, well im gonna b putting on my new 3in o2 housing and i was wondering for the people that have done it, when bolting it up to the exhaust manifold is there studs that come off of the manifold to hook it to or do u align it up to the hole and use just a bolt that screws in and holds it in place, im asking because im missing 2 bolts and i cant really see up in there, so im tryin to figure out what is there so i can buy new bolts or studs and i also need the size of the bolts..Please help
