Invidia offers an affordable, high-quality catted downpipe for the 2008+ STi/WRX. Whether you need a catted downpipe to comply with emissions laws or you just prefer the sound of a catted exhaust, you will be pleased with this unit. The divorced feature of this downpipe separates the exhaust gasses from the wastegate away from the turbine in order to promote smoother flow and in turn more horsepower and torque. On some 2008+ STi/WRX applications, over-boosting issues have been caused by free flowing exhausts. Most tuners will recommend a catted downpipe just like this to control boost creep. With the extra o2 bung for a wideband sensor, your tuner will surely be pleased with your purchase of this downpipe!
