Subaru WRX STI Performance Exhaust - Invidia - Q300 - Stainless Tips - `15-`27. This premium cat-back system delivers a deeper, more refined tone and durable stainless construction for your WRX STI.

Built around Invidia’s Q300 mufflers, this exhaust balances daily comfort with a richer soundtrack under throttle. Stainless steel piping and single-layer quad stainless tips offer long-lasting performance, while mandrel bends and carefully placed resonators help control drone and promote smoother flow. Designed as a direct bolt-on for the 4-door chassis, it maintains proper clearances and uses factory-style hangers for straightforward installation and consistent fit.
