Valve off = more torque but gains less power overall?
Valve on = less torque but gains more power overall?

It has been raining crazy here with messed up traffic so I haven't really drive my car hard enough to see the difference.
This is good news for me! I was worried that the off position would be too loud still. But that sounds good. I'm excited to put it on now. Now all I need to do is take delivery of my car

The off position is fine... yes only marginally louder than stock (but still better)

ok cool. I will just reserve the the on position for the highway and back roads. I really like the ability of the valves opening and closing.

OP take more videos outside. Reving an exhaust inside makes it sound different

Sickkk

Doesn't sound as raspy as in their promo videos which is strange. Still sounds so good!
