N*Power is another cheap poor quality manifold from China no doubt. They also dont even state what grade of stainless steel it is either which is a lucky dip as some forms of ss are more heat, hardening and corrosive resistant than others. Most stainless shouldnt even be used for hi-temp applications like turbo manifolds and dumpipes let alone carry the weight of the turbo and exhaust system. For a quick fix yeah why not buy it and see how long it lasts but for durability and strength you cant go wrong with a decent cast or steampipe manifold.
