Fabspeed Corvette C8 Z06 Supersport Exhaust System | Cicio Performance

This valveless exhaust system has the bark to match the Z06 bite. With an authoritative rumble at idle and cruising speeds, this exhaust system will wake up your LT6 engine like no other cat-back exhaust out there.


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 neighbors 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 addition 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.
