It’s going to sound great when you’re under decent throttle pressure and scream at WOT.
When you’re at idle or cruising it will sound almost stock with the OEM NPP when the valves closed.
I have a similar setup (Corsa) and want more sound volume at idle and light throttle so I have the Corsa Extreme Variable (w/ NPP Valves) going on tonight. I’m also adding the Mild2Wild so I can keep the valves open or closed regardless of the throttle position.
why didn’t I just add the Mild2Wild or pull the fuse to have the stock NPP valves open all of the time? The drone was pretty bad cruising and sounded like crap. The Corsa will eliminate all the drone.
