Default AWE switchpath exhaust

Anyone out there running the AWE switchpath exhaust? Looks like an interesting option, but I am worried about droning due to the fact that it doesn't have the resonators.

If it's anything like the version for the 8V S3, it's the valves that take care of controlling drone, that is, no drone when closed.

im running it on my s4 and love it. The drone is almost non existent with valves closed until you reach 80. it’s only slightly louder than stock. Valves open is brain shaking.
