Tru I forgot gsr = 2 piece ...neways what threw me off was the 14 hrs endyn, port flow n them guys only charge 450-500 with there labor thats only like 6-8 hrs of total work & they flow it.I dont care how good someone thinks there eye is id never trust someones eyes on porting thats like trustin the butt dyno vs a real dyno.

But hey if it works it works
