GrimmSpeed Downpipe to Catback 3" Gasket - Subaru/Mitsubishi Evo - 2X Thick
GrimmSpeed built its reputation on solving the small but critical problems that plague aftermarket Subaru and Mitsubishi builds, and this gasket is a textbook example. The 2X Thick 3" 2-Bolt Gasket (SKU GRM076001) is a 12-layer stainless steel design engineered to stop the blow-outs and leaks common with thinner aftermarket gaskets at the downpipe to catback joint.
This listing covers any Subaru or Mitsubishi Lancer Evolution vehicle running a 3" 2-bolt aftermarket exhaust flange between the downpipe and catback section. It's a universal fit gasket designed to replace factory or worn aftermarket gaskets across compatible exhaust systems, not a single specific chassis.

- 100% thicker than OEM gaskets
- 304 stainless steel fire-ring for improved seal and heat resistance
- 3" bore, 2-bolt flange pattern
- Designed for downpipe to catback exhaust joints
- Fits all 3" aftermarket Subaru and Evo exhaust systems using this flange style
Vehicle compatibility and flange sizing details are provided in the tabs above. Please confirm your exhaust system uses a 3" 2-bolt flange before ordering.
