Hi everyone, I'm trying to build a new intake for my GTP and have no idea how to actually attach the piping to the throttle body. I originally thought i would just use a coupler but after removing the stock intake tube i noticed that there is a weird "lip" that keeps it attached. I've seen people build their own intakes on here before but none of them seem to address this and I'm honestly clueless. Does anyone have any tips to get around this?
