found these on the ebay 250 plus shipping looks like a tubular log wondering if neone has ne experience with this company and if this design would be better then goin with a cast manifold. im shooting for the 300+ whp range in d16z6 wondering if it would be worth it or just stick with the cast only thing on the cast is the waste gate flange is only on one runner wondering if that really makes much of a difference if it matters im running a t3/t4 w .60 trim i heard the cast and mini rams would b better for low to mid range over the ramhorns dont no how tru that is either but neways thanks for all the help
