When it comes to custom exhaust work, control is everything. Whether you're fabricating a full system or upgrading your own ride, Vacuum Exhaust Valve Kits have become one of the most popular add-ons in the performance and fabrication world — and for good reason.
With our new and improved 304 Stainless Steel Vacuum Exhaust Valve Kits, you get the perfect blend of sound, flow, and flexibility. Here’s why these are becoming essential for both fabricators and car enthusiasts.
What Is a Vacuum Exhaust Valve?
A vacuum exhaust valve is a vacuum-actuated butterfly valve installed within the exhaust system.
-
When the valve is open, exhaust gases flow freely, creating a louder and more aggressive tone.
-
When the valve is closed, sound levels drop significantly, keeping your setup quiet and street-friendly.
This simple mechanism gives drivers the best of both worlds:
-
Open valve: Maximum noise, free-flowing tone
-
Closed valve: Quiet, controlled, neighbour-friendly driving — perfect for late nights
All activated at the press of a button.
