brand names really don't matter. it's the design that matters. a divorced waste gate side is always better. just mae sure it's a quality company and you will be fine.

its a blank plate design which covers the wastegate and restricts the flow a lot more than other aftermarket downpipes.

if you were to buy it, you might as well gut your stocker and go stealth
