Stock vs hdev exm manifold for 380bhp

[doggy]

Hi guys, I am running H dev exhaust manifold for 5 years now. I always had problems with exhaust leak, but never got the time to sort it.
Now I am making a new elbow and downpipe, and want to solve this problem. Now I was thinking maybe go back to stock sr20 ex manifold?

Is it good for 380bhp, will there be any difference in the car behaviour? I have Garrett GT2871R, a bigger option on garrett site, but with smaller ex case, 0.64.

Will increase response down low and will avoid any future cracking issues etc will cope with 380hp fine

The stock one is cast it will never crack unless you hammer the shitb out of it. Plus you will regain some low down grunt
