Product Description
Fitment Information: 2022-2025 Subaru WRX Features: The crème de la crème of the cat back exhausts for your WRX! The R400 has become the benchmark for catback exhausts systems for these cars. With fantastic fitment, finish and design, your neighbors will hate you but you will love your car so much more. Much rumble, such wow. Exhaust Tips: Quad 3.5" inch Burnt Single Wall 304 Stainless Steel construction 3" inch resonated Midpipe into a 2.25" inch Y-pipe for increased flow while maintaining back pressure Four straight-through mufflers Exhaust hangers welded onto the OEM locations to make for a direct fitment New gaskets and hardware are included Excellent pick for your 2022 or 2023 WRX. This exhaust is middle of the road for noise level. Quieter than the N1 and louder than the Q300 Series. If you're running the stock downpipe you'll need a downpipe to catback adapter. My top pick is the grimmspeed 077046 If you want to stiffen up the movement of the exhaust you can also get 5 Perrin 12mm poly hangers, the stock hangers will also work.

FAQs
Which Invidia exhaust is best for a daily-driven 2022–2025 WRX?
Q300 for the quietest cabin and minimal drone. Choose R400 if you want a deeper, more aggressive note but still plan to daily the car. The N1 is the loudest and best suited to enthusiast/track builds.
Does the Invidia R400 drone on the highway?
Many owners report some cabin resonance around steady-state cruise (certain RPM ranges). Overall it’s more livable than the N1, but not as quiet as the Q300. Mounts, resonators, and other mods (downpipe, cat, intake) can influence drone.
How does the Q300 sound compared to stock?
The Q300 keeps things near-OEM volume at idle/cruise with a deeper, richer tone under throttle. It’s the most conservative of the three.
What tip options are available?
R400 typically offers quad 101 mm tips (polished stainless or burnt titanium). Q300 offers rolled-edge tips with a more OEM look. N1 variants vary by configuration and finish—check product pages for exact specs.
Material & build quality?
Invidia systems are generally SUS304 stainless steel with TIG welds, mandrel bends, and include hardware/gaskets for bolt-on fitment to the VB chassis.
Will I need tuning after installing a cat-back exhaust?
A cat-back on its own typically does not require a tune; however, pairing with other mods (downpipe, intake) may benefit from calibration. Always follow manufacturer guidance.
Is the exhaust street-legal?
Legality varies by state/municipality (noise limits). The systems are designed for fitment and performance, but local sound laws apply. Check your local regulations.
Fitment for 2022–2025 WRX (VB)?
These Invidia cat-backs are designed for the VB chassis (2022–2025 WRX sedan). Always confirm trim/transmission notes and tip cutout compatibility on the specific product page.
