Its a flange and a clamp. How badly could someone fuck that up? I can see for a precision piece, but for shit like that, who cares? Also, I don't know about rigidly connecting intercooler pipes. Silicone flexes and allows for movement between the motor and the piping/intercooler.

But hey, its your money. Spend it how you see fit... I'm not gonna tell you how to build your car
