Default Shorty headers on mid mount twins LSX 5th gen

I've got a 2010 camaro i built a lsx and got a midmound agp twin turbo kit with garrett gtx3582r's. The 6 bolt heads require shorty headers. I know ARH are the nicest pieces for the 5th gen but the collector is 2.5 and i found some flowmaster shorties that have 3" collector. I also found some hedman that seemed comparable to the arh. What's ya'lls take on shorty headers on midmount turbo's and what is my best option r if it even matters

I'd sooner go for a 2.5" or smaller collector than the 3"

And what is the reasoning for that?

To keep exhaust velocity up and spool the turbos quicker.
No need for a 3" collector.

A 2.5" collector supports a tonnnnn of power!

As would even a 2" collector.

Look at the size of the turbine inlet on a GT35...it'll be tiny. Maybe 1.5"

Unless looking for insane power levels, it's all about keeping gas speeds high, huge tubes are not needed or wanted
