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 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%

Fitment is unmatched

I have been admiring this catback online for almost a year and pulled the trigger when they gave us the stimulus 10% and now that I have it I would have paid full price and not cried. I had a Nameless axle back which rattled my brain. Sound quality is amazing, loud enough to hear the exhaust with the windows up, but quiet enough to prevent getting the middle finger from your neighbor at 2AM. Oh and ive never been happier over the old exhaust, if you're beyond the "how loud can I make my car" phase and want something a little more mature with good power, this is the one you want. Fitment is the best fitment ive ever gotten from an aftermarket exhaust, its a handmade piece really and fits like someone made it tailor-made to your car. The exhaust hangers are VERY STIFF so as a result you can kind of feel a little vibration in the floor boards (not a ton and you can use the rubber mounts if it bothers you) but that's actually awesome because you don't get that "wobbly muffler" when you rev up your car. REALLY WELL MADE! MADE IN THE USA!!!
