Recently while racing, my Y pipe from the TB popped off and the car died. I pulled over and checked it out, and the rubber seal that goes inside the y pipe and around the TB, the ring on the top of it that seals the outside of the Y pipe is missing part of the seal, so i ghetto rigged it, drove it home, and its been sitting since. What is this part called? part #? would i have to order it from mitsu? or should most auto parts stores carry it....?
