The Fabspeed Valvetronic Cat-Back Exhaust System is the ultimate exhaust solution for the C8 Z06. It provides the same screaming sound that our Supersport X-Pipe exhaust has while also allowing the driver to quite the exhaust down using the factory exhaust loudness settings. It’s totally plug-and-play with the factory exhaust valve system.
Our design process started with 3D scanning the entire OEM exhaust system using our CREAFORM 700 Handscan so that we could make a complete Solidworks 3D model of the exhaust. We then designed the exhaust and fixtures using that model so that the exhaust fit perfectly to OEM standards. After multiple revisions for sound and dyno testing we decided to use our signature cast X-Pipe to tie the two cylinder banks together for exhaust scavenging and to defeat resonance. The valves are mounted to CNC’d plates that resist heat and keep the electronics working uder extreme conditions. The piping is mandrel bent from T304 Stainless steel, and we use ultra high temp heat wrapping to keep temps in the engine bay down.
SOUND:
This incredibly versatile exhaust is able to go from tame cruiser, to thoroughbred race car with the press of a button. With the car set to the loud exhaust mode (valves open), you’ll be treated to 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. With the Z06 set to quite mode (valves closed), it’s totally drone free and you can easily have a conversation in the cabin just like the OEM exhaust.
