The Tomei is titanium(obviously), which is why it sounds so different. There is also thinner gauge metal used, which is a factor as to why it's so loud. Several people have also had theirs crack. Tomei is good stuff, but thin metal being heat cycled(and scraping underneath a low slung car) is bound to give at some point.
