  • Custom GrimmSpeed muffler – the design offers a deeper, more refined tone over OEM
  • Quad 3.5" double-wall, angle-cut tips - our most commonly requested configuration
  • Resonated or Un-resonated options - the choice is yours!
  • 304 Stainless Steel construction - genuine American 304SS material to withstand the elements and abuse
  • 1/2in thick flanges - all flanges are laser cut from 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 adjustable polyurethane hangers - these hangers keep your exhaust where it needs to be, adding ground clearance, 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
  • GrimmSpeed Lifetime Warranty - buy knowing that we stand behind our products and customers 100%
