Invidia 02-07 WRX/STi 80mm Full Titanium Cat-back Exhaust

Crafted from full titanium, this 80mm cat-back exhaust system from Invidia is built for the 2002-2007 Subaru Impreza WRX and STi. Titanium construction means it's significantly lighter than stainless steel or aluminized steel alternatives, which can make a noticeable difference in overall vehicle weight. This system is designed to replace the factory exhaust from the catalytic converter back, aiming to improve exhaust gas flow and alter the sound profile of your engine.

The 80mm piping diameter is larger than stock, allowing spent gases to exit the engine more freely. This can contribute to a slight increase in throttle response and a more aggressive exhaust note. The titanium material not only sheds weight but also offers good resistance to corrosion, though it will develop a unique patina over time with heat exposure. The system includes the necessary components for installation, designed to bolt up to the factory catalytic converter outlet.

When installing a larger diameter exhaust like this, you're looking for a more direct path for exhaust gases and a distinct sound. The titanium construction is a key feature here, emphasizing weight savings for performance-minded enthusiasts. Ensure you have the proper tools and clearance for installation, as working with exhaust systems can sometimes require adjustments for a perfect fit.
