Dual Exhaust Question.....

[Volume_Civics]

I have recvently purchased a truck with a cheap dual exhaust kit on it. It doesn't seem like a true dual exhaust. There is a Y pipe that comes off of the what <B>looks</B> like stock muffler. I no longer want the noise. I was wonder if I can just cut the Y pipe, leaving a couple of inches of pipe for the tail of the muffler. Will this cut the noise to stock standards? Or does the truck have an aftermartket muffler that I need to replace with a stock one?
