The valve opens at vacuum. This allows you to mount it directly on the exhaust and it will close as soon as there is a vacuum. Easy to mount, even without control, you just need to pull a silicone hose from the engine compartment.

You can advantageously use Y-piece for exhaust to make distribution / outlet from the exhaust. You can also use this Split muffler if you want it to sit right after a muffler under the car. If you want to make a split output on your exhaust yourself, you can use stainless steel tubes to build it with.

If you want to make it easy to disassemble and install the system you can buy our v-band flanges or connector for exhaust .
