what is the y-pipe? i hear quite a few people refering to it and that its made of plastic on the US fd's but on the efini's it was metal. where is it located and does anybody have a picture of what it looks like. the reason im asking is because yesterday i pulled apart all the intercooler and intake piping to try and find a boost leak. i fixed the leak but one thing i remembered is that its very common for the ypipe to crack. i saw something that looked like a y shape but it was metal the thing im talking about is the piece that the top intercooler pipe runs to. i was wondering if that is the y pipe or is the ypipe somewhere else?

ok so the y pipe is metal on all fd's but its an improved design and made of aluminum on the efini? and on the us fd's the crossover is plastic where on the efini its aluminum?

Yes, and there is a rubber coupling connecting the stock y-pipe to the plastic crossover, where the efini is an aluminum y-pipe bolted to an aluminum crossover.
