Help with Y pipe
 

Hello guys, I recently bought this used Y pipe and on the side that connects to the mid pipe, there are two studs where a nut falls in place to tighten the mid pipe to Y pipe, anyone know the pitch and size of the nut?, I know it’s a 14MM but I have no idea what the pitch of it is, also if you guys could share the link directly to it that would be even better, thank you!

most likely 1.25

Is it an OEM y-pipe...? If so, I'd second the 1.25 pitch recommendation. Probably M10.

I'd hit up a Lowe's/Home Depot/any auto parts store and buy a few of different sizes & pitches and return whatever doesn't fit.

Thanks man, ended up using a few nuts from my friends is300 partout car, somehow I actually found ones that fit just perfect
