GrimmSpeed - Subaru 11-14 WRX / 08-14 STI - Resonated Catback Exhaust System

With so many catback exhaust options available, our goal was to create a unique, refined sound in an extremely high-quality hand-welded system. We've been affectionately referring to it as the “gentleman's exhaust” around the shop due to its mature tone. Available in both resonated and un-resonated options, our catback will be the perfect addition for any enthusiast looking for increased performance with a sophisticated exhaust note.

Quick Specs

• 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 the 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%
