SLP Y-Pipe

[Cerwin Vega Fan]

I have chance to get an SLP Y-Pipe (new unused) from someone at a good price. What I'm wondering is will this Y-Pipe bolt up to headers if I choose to go that route at a later time? I'm guessing this Y-Pipe is very similar to the one used in conjunction with the SLP shortys so would it bolt up to a pair of SLP shortys?
