I crawled under the truck to check myself also. The Y-pipe to the muffler is 3". The way they squashed the pipes together going into the stock Y, it looks like a 3". But the individual pipes themselves are 2.25" apparently. I didn't measure them, but they are most definitely not as big as the 3". So now the Y pipe will be dual inlet to allow those pipes to be connected individually and opened up so the truck can fart better than that time I had too much Taco Bell..........JK, JK
