Invidia Titanium Catback Exhaust - Subaru WRX 2002-2007 / STI 2004-2007

If you're in the market for both weight savings and added horsepower, then the Invidia Titanium Cat Back Exhaust Systems really aim to please. This exhaust system has been designed with minimal bends to reduce the amount of exhaust turbulence during acceleration which allows the engine to exhale the exhaust gasses with less restrictions. This means you will have improvements in throttle response, along with increases in both horsepower and torque. 

This exhaust has been fabricated from titanium and features 80MM piping. The total shipping weight is just above 24LBS. The exhaust hangers are welded onto the OEM locations so you don't have to perform any further modifications to the body for fitment. New gaskets, hardware, and a silencer will be provided to make this a direct bolt-on exhaust system.
