GrimmSpeed Resonated Catback Exhaust System - 11-18 WRX/STi



Fits These Applications:
2011-2018 Subaru WRX Sedan
2011-2018 Subaru STi Sedan

With so many catback options available, GrimmSpeed's goal was to create a unique, refined sound in an extremely high quality system. This particular design is able to fit both EJ and FA WRX and STi sedan models from 2011-2018.

  • Custom dual outlet mufflers - dual perforated tubes offer quieter, more refined tone
  • Quad 3.5" double-wall, angle-cut tips - the most commonly requested configuration
  • Resonated or non-resonated options - the choice is yours, although we recommend resonated for the FA20DIT and un-resonated for the EJ
  • 304 Stainless Steel construction - genuine American 304SS material to withstand the elements and abuse
  • 1/2" thick flanges - all 7 flanges are laser cut from the same 1/2in thick stainless plate for perfect sealing, easy installation and extreme durability
  • Flex section - your motor and mufflers are both mounted using rubber or poly mounts and can move independent of one another - if there isn't a flex section or donut gasket allowing relative movement, there's a much greater likelihood of damage to your exhaust or turbo
  • Custom polyurethane hangers - these hangers keep your exhaust where it needs to be, freeing you from rattles, melted bumpers and so on
  • TIG welded - each catback is hand TIG welded just across the hall from the engineering offices that they were designed in, ensuring craftsmanship that does our Lifetime Warranty justice
