Aite guys seems like im running into alot of problems now that its about done. Now i've got a header leak at both exhaust flanges where the collector bolts up to the exhaust flange. Not only is this a leak, its awful!! is there any way that ya'll know of to fix this since there is a donut gasket in there and i think it might have gotten hot and blown it out? and im gonna put locking nuts on it since it was almost hand loose! also gonna use copper rtv around the new donut gasket to help make a better seal!!! but is there anything else i can do to prevent this again. i know i was expecting to have to torque them down every once and a while but not have the collector/flange seperate!!? its in front of the o2 and is causing is to run lean from the extra air in the pipe. its throwing the new tune off!!! BAD!!!
