Which size Y pipe?

[edemce]

I tried to search but couldn't find it on the search button so if this is all over the forums please excuse me.

I want to get a Y pipe to replace the stock crushed one, just not sure on sizing.
I'd want to get it done when i install the Mufflex DOD18M muffle and figured i would kill 2 birds with 1 stone.

So does anyone know what size i need for the inlet and outlet options?

My vehicle is a 2015 CC 4x4 Sport 5.7L.

Thank you!

Prolly going to be 2.5 in and 3 out I would assume someone correct me if I'm wrong

It's 3inches. It doesn't turn into 2.5 till after the muffler

In all honesty, I would save your money on the Y-pipe unless you are doing headers. While the factory Y-pipe is pinched off, the stock manifolds just don't move enough air to benefit much from a better flowing y-pipe. To answer your question though, it is a dual 2.5" inlet and a single 3" outlet.

So that would mean there is no point in adding a better flow muffler accept to change the sound.

Correct. A muffler swap is only good for about 5hp if that.

Thank you, i plan to do headers in the future.
