The COBB x Korsh engine back package combines COBB's proven engineering with Korsh precision manufacturing for maximum flow, aggressive tone and power gains from the turbo outlet all the way to the rear bumper.

It includes everything needed for a complete engine back upgrade on the 2011–2014 WRX and 2011–2021 STI: Korsh by SSI unequal length headers, a Korsh downpipe and the COBB cat-back exhaust with dual mufflers and polished tips.

Why COBB x Korsh?

• Unequal Length Headers – Preserve the iconic Subaru boxer rumble.
• Improved Throttle Response – Reduced backpressure lets the turbo spool faster.
• Power Gains – More horsepower and torque throughout the rev range.
• Mandrel-Bent, TIG-Welded – 304 stainless steel resists corrosion and heat damage.
• Dual Muffler Cat-Back – Aggressive sound without drone, polished tips.
• Weight Reduction – Lighter than the factory exhaust components.

• 1 x Korsh KOR-EXHDP-08 high-flow downpipe (gaskets and stainless hardware)
• 1 x Korsh by SSI KOR-MAN-UEL-001 unequal length headers (gaskets, studs and heat wrap)

Important Notes
