hey guys, does anyone know the size of the nuts that went on the bottom of the y-pipes where it connects to the manifolds? one recently fell out on me somehow. the other nut holding the y-pipe in is 14mm, but when i try to use a 14mm on the other side it doesnt fit for some reason. any idea what the correct size is? thanks for the help!

 

anybody? even a guess? im hoping to get this done tomm

 

Try a M10X1.5 nut.

 

thanks! ill defenitly stop by the auto store tomm and see what works, ill report back here with my findings
