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.
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 have 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, exhausts that are to 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 experience that makes you want to stand behind them as well.
