Pipe for OS 70SZ-H?

[HeliEddie]

I'm toying with the idea of swapping my YS 61-S for a OS 70SZ-H in my Raptor 60 V2. If I do, can someone recommend a pipe?

Thanks.

MP2 works just fine. I did the same thing, had a YS61-ST2 in my old X-Cell and ones worn out I replaced it with the OS 70 and a MP2 that I had in stock.

Which MP2, the 50 size or the 90 size?
