got a evo ms diverter valve in my car, my buddy tells me you can switch/swap the two hoses on the diverter and it will give it a different sound...is this true or not? let me know

Sounds like you're chirping tires. I've heard this is the loudest DV on the market. True?

From what I have heard installing it in reverse, switching the charge and return around, will further "enhance" the sound of it. no idea if its true.. try it and see what happens.

Don't aftermarket valves need to be installed reverse of the stock ones anyways?

i put mine in the same as the stock one, because i thought for some reason it was a bad idea to install it switched around

Most piston type valves are designed to have the boost pressure at the bottom of the valve. The bottom of the piston in the Evo valve is also designed to help the piston seal. Installing it with the boost hitting the bottom of the piston also increases how quickly the valve opens.


Changing the way you have it installed shouldn't change the way it sounds since the air is till flowing thru the same spot in the valve and past the bottom of the piston.

thanks for the info mike [up]

so diaphragm-style valves such as the APR diverter are best installed normally, and piston valves are most optimal with the pressure hitting the bottom of the piston rather than the side?

i put a cone filter setup in my car today and now i can hear it for sure. i like it a lot, the sound is actually a lot quieter than i anticipated, which is good because if it was really loud it would be annoying.

i used to have an Evoms DV and then I got a 007 and its a bit louder and had a crisper sound. They are basically the same exact thing tho.
