Default Exaust RPO Code

I'm getting a high flow cat and want to know if there is a RPO code to tell me the diameter. I've heard I may have either 2.25" or 2.5" but I need to know for sure.

SSEi'* came with 2.5". As did NA SSE'*.

SC SE'* came with 2.25, despite having the L67.

Your LSS is an unknown until you measure it. There are no RPO'* that will tell you the diameter.
