Boost Activated Loudvalves

Get all the power and quick spooling of an open downpipe, or the nice quiet sound of a stock exhaust its up to you...

 These cutouts open completely automatically, no switch to forget to turn on, no climbing under the car to open your manual cutouts , no electric motors that keep burning up.  No more compromising between an enjoyable ride and getting the most power out of your setup. Valves fully open at 6-7psi, you can also have them to open at higher boost pressure by using a boost controller.

Slip fit inlet and outlet makes for easy welding. then just run a boost reference line to the valve and your done.

 Notice: Valves may have slight exhaust leak.  the majority of our cusotmers say they dont notice a leak, but it could occur depending on how restrictive your exhaust is
