Altezza 3sge factory exhaust piping

[InterUni]

Hey guys I’m new here so I’m not sure what I’m doing but wondering if anyone knows the factory piping size on the 3SGE motors? Gonna do a resonator swap but deciding if I’m gonna go for a 2.5 inch or 2.25 inch diameter piping

thanks in advance to any help

Pretty sure it's 2.25", same as the IS200. The backboxes are the same and they're both 2.25". Not sure about the rest of the exhaust but the IS200 has 2.25" all the way through, I imagine the Altezza is no different.

I know the stock piping is 2.5".
