Fitment Information
- Subaru Legacy XT (2020, 2021, 2022, 2023, 2024, 2025)
- Subaru Legacy Sport (2023, 2024, 2025)
- Fits Automatic Transmission Only
Emissions Compliance
- 50 State Legal - This part is legal for sale and use on Emissions Controlled Vehicles in all 50 states when used in accordance with the manufacturer's application guide because it has a California Air Resources Board (CARB) Executive Order (EO) number:
Specs & Features
- Bulletproof Construction: Made from CNC Radiused 6061 Aluminum to eliminate the cracking and failure issues inherent to the stock plastic tubing that degrades with heat.
- Flow Optimized: Features an integrated billet transition that smoothly expands from 2.5" to 2.75", increasing air volume while retaining critical clearance for larger aftermarket radiators.
- The "Click" of Security: Utilizes a bespoke Machined Retaining Clip with a ball detent mechanism that locks the pipe securely to the turbo housing—far superior to the flimsy stock connection.
- Stealth Appearance: Finished in a durable Wrinkle Black Powder Coat that matches the factory intake manifold, keeping the engine bay looking professional and "OEM+."
- Broad Compatibility: Designed to fit the entire turbocharged FA24 family, including the 2022+ WRX, 2019+ Ascent, and 2020+ Outback XT / Wilderness.
- No Tune Required: Completely safe to run on the Stock Tune or COBB OTS Maps, making it the perfect reliability modification for a daily driver.
Product Description
Modern Subaru engines like the FA24 are engineering marvels, but they have a weak link: plastic plumbing. To save costs, the factory installs a plastic charge pipe that becomes brittle after repeated heat cycles. Eventually, the flange cracks or blows off, leaving the car with zero boost. The COBB Tuning Charge Pipe is the permanent fix. By swapping to rigid, high-grade aluminum, COBB ensures that the boost pressure actually makes it to the intercooler, regardless of how hot the engine gets.
Making a bigger pipe is easy; making one that fits is hard. COBB engineers designed a unique Billet Transition piece that steps the diameter up from 2.5" to 2.75" right at the intercooler connection. This tapered design maximizes flow velocity but keeps the lower section slim enough to clear the cooling fans. This smart design means you won't have fitment headaches if you decide to upgrade to a massive aluminum radiator later on.
The connection at the turbocharger is the most critical point. Many aftermarket pipes use cheap couplers that slip. COBB machined a custom Anodized Retaining Clip featuring a ball detent system. When you install this pipe, it locks onto the turbo housing with a positive engagement. Combined with high-quality 5-Ply Silicone Couplers, this system is virtually leak-proof.
This is "preventative maintenance" that doubles as a performance upgrade. Whether towing a trailer with an Ascent, off-roading in an Outback Wilderness, or carving canyons in a VB WRX, the last thing a driver needs is a blown charge pipe. COBB provides the peace of mind that comes with metal parts. It improves airflow, prevents failures, and looks incredible under the hood. Don't wait for the plastic to crack—upgrade it now.
