Invidia 15+ Subaru WRX/STI 4Dr Q300 Twin Outlet Rolled Stainless Steel Quad Tip Cat-Back Exhaust

What you get with this Invidia Q300 cat-back exhaust system is a complete setup designed to bolt onto your 2015-2016 Subaru WRX or WRX STI. This includes the mufflers and the exhaust piping from the catalytic converter back, featuring a twin outlet design with rolled stainless steel quad tips. It’s built to give your car a more refined exhaust note and a distinct visual upgrade, especially if you're looking to replace an older or damaged system, or simply want a different sound and appearance.

The Q300 series from Invidia is known for balancing performance with a more street-friendly sound profile, meaning you get an improved exhaust tone without excessive drone or loudness that might draw unwanted attention. The construction uses well-built stainless steel throughout, which is a solid choice for resisting corrosion and ensuring longevity, especially in areas where road salt or moisture is common. The quad tip design with rolled stainless steel edges adds a sporty and aggressive look to the rear of your WRX or STI, making it stand out.

When installing a cat-back system like this, you're typically looking at a direct bolt-on process, meaning no welding or cutting is usually required, making it a manageable project for many DIYers or a straightforward job for a mechanic. This system is designed to fit the 4-door sedan models of the WRX and WRX STI from 2015 and 2016. Ensure you have the necessary tools and perhaps a helper, as exhaust components can be heavy and awkward to maneuver into place.
