seems like a pretty good price, but im not sure about the domes, they are prolly off shelf domes.
the porting stage2, i dont know what that means. if you ask them what pipes to use, they will prolly say trinity pipes.
so you already bought them ?
i had t5 on my serval, and now shearers, and the shearers are better everywhere than the t5 and pull way harder and longer. and i trail it as well.
