Cobb 2.5" 2-Bolt Exhaust Gasket for 2002-2021 Subaru WRX/STI & Mitsubishi Evo

The Cobb UNI-001-253 2.5" 2-bolt exhaust gasket delivers a multi-layer stainless steel seal for 2.5" exhaust joints on Subaru WRX, STI, Forester XT, Legacy GT, Mitsubishi Lancer Evolution, and universal applications. Raised sealing beads crush under torque for a tight, leak-free connection that holds up in performance setups. This direct replacement fixes worn or damaged gaskets in downpipe-to-catback and turbo outlet connections.

Key Features

  • Multi-Layer 304 Stainless Steel: Resists corrosion and handles high exhaust temperatures
  • Raised Sealing Bead: Compresses on both sides for a reliable seal when bolts are torqued
  • Universal 2-Bolt Design: Matches 2.5" flanges on Subaru EJ/FA engines, Evo 4G63/4B11, and aftermarket systems
  • Leak-Free Performance: Locks in backpressure and stops exhaust gas escape
  • Made in USA: Built to exacting standards with 12-month limited warranty

Product Notes

  • One-time use gasket; replace after disassembly for maximum seal integrity
  • Inspect flanges for flatness before install to ensure proper crush
  • In stock item ships in protective retail packaging

Installation Notes

  • Professional installation recommended.
  • 15-30 minutes install time; clean flange surfaces and torque bolts evenly to 25-30 ft-lbs
  • Compatible with OEM and aftermarket 2.5" 2-bolt hardware; no additional parts needed

Exhaust gaskets create the leak-free seal between your exhaust manifold, headers, downpipe, and catalytic converter. Quality gaskets are critical for preventing exhaust leaks that reduce power, increase emissions, and create safety hazards in the engine bay.
