I have a 16 Tahoe 5.3. Does this apply to me? If so, is the the same concept as pulling the fuse on NPP equipped Camaros and Vettes? The valve stays open all the time?

No, our valve is strictly mechanical.

Yes, you have one.

No CEL or any other issues right?

No, bus system is as quiet as a church mouse...

Hmmmm. Came home from work, manually opened the valve, slid on the 2” automotive hose clamp and tightened it down

Not to be a *****, but 0 difference in sound. Just curious did anyone’s car get noticeably louder or a deeper tone?

Yes, although minor! First I climbed under and checked the rotation both ways with the engine running prior to clamping and made sure.

Ran it this way for a while and eventually just cut it out and welded a piece back in.
