Fitment

Please Note: Official COBB fitment: 2011–2014 Subaru WRX sedan and 2011–2014 Subaru STI sedan. The approved STI bucket covers 2008–2014 STI, but this exact exhaust is sedan-specific for 2011–2014. Custom ECU calibration is required; product is discontinued and not CARB approved.

Description

The COBB 3-inch Titanium Turboback Exhaust combines a stainless steel high-flow downpipe with a lightweight Grade 4 titanium quad-tip cat-back for 2011–2014 Subaru WRX and STI sedans. The system reduces exhaust restriction, improves turbo response, and delivers a deeper boxer exhaust note through mandrel-bent tubing and twin straight-through mufflers, with back-purged titanium welds for durability and a premium finish.

• Fits 2011–2014 Subaru WRX sedan and 2011–2014 Subaru STI sedan
• Grade 4 titanium cat-back construction with back-purged welds
• Stainless steel downpipe with a 200-cell high-flow catalytic converter
• CAD-designed cast turbo outlet promotes smooth exhaust flow
• CNC mandrel-bent tubing
• Quad 3.5-inch blued titanium tips with COBB logos
• Custom ECU calibration is required after installation
• Discontinued by COBB; remaining inventory only
• Not CARB approved; verify local emissions requirements before purchase and installation
