Invidia's divorced style downpipe helps exhaust gas exit quicker and more efficiently through the exhaust system. This provides for betting spooling characteristics and more power. Upgrading to a higher flowing, 3" downpipe on the Subaru WRX and STI comes with significant power and torque gains. Invidia uses 304 stainless steel exhaust piping and mandrel bends each pipe so the gases travel quickly and smoothly through the new piping.
