im fabricating my 2.5" intercooler pipe and I have the cold side done and ready to be welded. my question is should I have it all welded one piece from the throttle body to the intercooler which is my current choice or should I make it a two piece for the cold side with a hump coupler between the two pipes to give it more movement? my main concern is with the engine movement I don't want a intercooler coupler to get torn off or blown off and I don't think they sell a hump reducer coupler for a 2.5" to 3"
