Agreed on sound. I went catless, and when the NPP is open, it's kind of ridiculous. Even a light blip on the throttle can startle people outside the car. WOT next to a concrete barrier or in an underpass is wicked.
Any drone with this setup?

Absolutely none with the valves closed. Sounds like my wife's tahoe.

Valves open you can hear it some at highway speed (70-80 mph), but it isn't what I would call drone. Less than my gen V camaro had with long tubes and corsa catback. Can still hold a conversation, talk on bluetooth, listen to podcasts, etc. I run valves open 95% of the time (really just close them in my neighborhood, if i see LEO...)

NPP is actually kind of amazing.

want to help me install mine ?

I see your info says you have a Sierra - is your statement on the 2" TSP for a Sierra or a Camaro (as this is a camaro forum - this could confuse some people)

I just bought TSP 2" headers in January and had to ding three header tubes on the drivers side (two for the steering shaft, one on the bottom for the motor mount)
