With so many catback exhaust options available, GrimmSpeed’s 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 refined tone. Available in both resonated and un-resonated options, their catback will be the perfect addition for any enthusiast looking for increased performance with a sophisticated exhaust note.
- 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 the 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%
Sometimes, this explanation is long and technical, especially where performance is concerned. This time, it’s simple. The GrimmSpeed engineering and manufacturing teams are known for designing and producing products that use high-quality materials, offer perfect fitment and superior craftsmanship. These catbacks are no different. If you’re tired of your catback rattling against heat shields, tips hanging too low, being crooked or uneven, exhaust that’s too loud, drone on the highway or materials that are rusting or failing, then we have the solution for you. Beyond the product, the GrimmSpeed customer service team is ready to help you with any questions or concerns you might have along the way.
We stand behind our products 100% and our goal is to offer you a customer service experience that makes you want to stand behind them as well.
