Exhaust Flap Valves

With many sports cars now offering dual mode exhausts, many aftermarket exhausts are looking to replicate this feature on their systems, allowing the vehicle to retain the ‘Don’t Upset the Neighbours’ mode as well as an improved raucous mode with a valve open!


Helical design and manufacture valves for supercar OEMs, using the best materials and manufacturing practices, with all valve designs rigorously tested prior to product release.


Our latest valves have the option of having a titanium or stainless steel valve body, matched with Inconel sub components where required.


Feel free to drop by the Helical Technology  SEMA 360 booth to learn more on why super cars only use ‘super’ Helical valves!
