anyone have any problems (past or present) with their exhaust manifold? something is definately wrong with mine but i'm not exactly sure what. the performance is still there, but now my car is louder from the engine bay and exhaust is comin out from the engine bay. it's not so loud that it wakes up the neighbors (i asked them believe it or not) but loud and annoying enough when your filling up for gas. could be a stud, or gasket, yet i don't think i cracked it. anyway, any help would be appreciated.
