Car is amazing as it is, but IF you are asking for one off ideas, then install a manual transmission please. I am looking forward to watching your build progress and thanks for sharing.

We are excited to share that we will be officially launching our Product suite for the Corvette C8 ZO6 tomorrow! Not only were we able to bring the first option to market, but we managed to pull unforeseen gains out of this already groundbreaking motor.

Check it out here - C8 Corvette - C8 Corvette Z06 (2023+) - Fabspeed Motorsport

We partnered with renowned Youtuber StreetSpeed717 (Mike), to take delivery, 3D Laser Scan, and reverse engineer Headers, 200cel HJS High Flow Cats, and our Non-Valved Supersport muffler. Our engineering team was able to put their foot down and complete this project in under 7 days, and we could not be more proud of the results.

No later did we finish Mike’s ZO6, did our great friend and NASCAR driver Matt Dibenedetto take delivery of his own in North Carolina! We wasted no time, flying down there to pick it up and cruising it back the 600+ miles to ensure a proper break-in! Our team has already gotten it stripped down and scanned in, and is hard at work developing a Valvetronic Cat-Back section to allow owners to retain all OEM drive modes and settings!

We at Fabspeed, are honored to have not only the first Modified ZO6 but the Second as well!

Fabspeed's Supersport X-Pipe Exhaust is the ultimate race focused cat-back setup for your Corvette C8 Z06. This exhaust system will wake up your LT6 engine like no other cat-back exhaust out there.

This all out race exhaust turns the Z06’s 5.5l V8 exhaust note into a thoroughbred race sound. With a much more authoritative rumble at idle, and our signature X-pipe bringing out the a high pitched wail that, dare we say, exceeds that of the Ferrari 458. This system is LOUD, so don’t be surprised when you wake your neighbers every Sunday morning. All this sound and performance comes at the cost of some interior drone. For a drone free solution, we are developing a valvetronic exhaust that will have the best of both worlds.


Combined with our Sport Cats, we gained 30 WHP at 4600 RPM and 36 ft/lbs of TQ at 4600 RPM. That's a gain of 33 HP at the crank! Peak horsepower also increased from our baseline of 640 WHP to 666 WHP and from 445 ft/lbs of TQ to 462 ft/lbs of TQ. When comparing apples to apples, in adition to the Sport Cat power gains, we saw additional gains of 16 WHP and 19 ft/lbs of TQ in the midrange and an additional 7 WHP at the peak. See our dyno graph above for more details.


  • Fits all Chevrolet Corvette C8 Z06 2023+ Models (Except EU Models)
  • Impressive dyno proven power gains of 16 WHP and 19 ft/lbs of TQ, 18 HP at the crank
  • Saves 35 lbs / 15.9 kg compared to the stock/OEM muffler
  • Retains the OEM “floating” exhaust tips, or convert to our Carbon Fiber tips and Carbon Fiber surround
  • Constructed from mandrel bent T304L stainless steel
  • Incorporates our signature cast X-pipe for superior flow and exhaust scavenging
  • Comes with Fabspeed electronic valve simulators that prevent a CEL
  • Designed from 3D scans of the OEM headers so we can achieve perfect bolt-on fitment
  • This cat-back system is emissions legal in all 50 states and the rest of the world (ROW)
  • No Check Engine Light guaranteed
  • Simple bolt-on installation, no cutting or welding required
  • All Fabspeed performance products are backed by the Fabspeed Lifetime Warranty
