Torque Solution Subaru Stock Downpipe to 3in Aftermarket Catback Exhaust Adapter 2002-2020 (TS-SU-479)

Fits select 2002-2020 Subaru Baja, Forester, Impreza, Legacy, Outback, WRX, and WRX STI.

The Torque Solution TS-SU-479 adapter provides a precision-engineered solution for mating a factory downpipe to a 3-inch aftermarket catback exhaust system. The OEM Subaru downpipe utilizes a smaller diameter and a donut-style gasket, while most performance catbacks feature a flat, 3-inch flange. Bolting these two disparate surfaces together without an adapter typically results in persistent exhaust leaks and poor alignment.

This adapter bridges that gap, ensuring a smooth transition and a leak-free seal. It is a critical component for enthusiasts who want to upgrade their exhaust sound and flow while retaining the stock downpipe. Designed for easy installation, it eliminates the need for custom fabrication or modification of the factory components.

• Bridges the gap between OEM donut-style downpipes and 3" flat-flange catbacks
• Ensures a leak-free exhaust seal and proper flange alignment
• Compatible with factory downpipe hardware
• Manufacturer Part Number: TS-SU-479
