GrimmSpeed Catback Exhaust System Non Resonated 2011-2014 WRX Hatchback / 2008-2014 STI Hatchback

With so many catback exhaust options available, Grimmspeeds goal was to create a unique, refined sound in an extremely high-quality hand-welded system. They'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.

Features:

• 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
• Non resonated
• 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%
