GrimmSpeed Downpipe to Catback 3" Gasket - Universal
GrimmSpeed has built a reputation for solving the annoying little problems that come with modifying a Subaru or Mitsubishi Lancer Evolution, and this gasket is a perfect example. Finding a genuinely leak free 3 inch 2 bolt gasket has always been a pain, and GrimmSpeed set out to build something that actually outperforms the factory part rather than just copying it.
This listing covers the GrimmSpeed 3" 2 bolt downpipe to catback gasket, suited to all aftermarket 3" exhaust systems using the common 2 bolt flange, across the Subaru and Mitsubishi Lancer Evolution platforms. Only one option is listed for this SKU, so no variant selection is required.
Note: this gasket is designed for the 3" 2 bolt flange pattern only. Confirm your exhaust system uses this bolt pattern before ordering, as 3 bolt style flanges will not suit.
Key Features
- 7 layer multi-layer steel construction
- 304 stainless steel fire ring for improved sealing
- 22% thicker than OEM style gaskets
- Designed for 3" 2 bolt downpipe to catback flanges
- SKU: GRM022001
Vehicle compatibility, OEM part numbers, and fitment notes are provided in the tabs above. Please confirm your exhaust system uses a 3" 2 bolt flange before ordering.
