You need to put some more PSI's to the car so we can see pressure at full tilt.

According to my phone, the car sits around 76db at idle with the windows up. This is with a huge Magnaflow and 30 pounds of insulation.

?? The point of that particular dataset was to show the difference between flapper wired open vs. flapper sprung normally.

The whole dataset including full power (270 whp) is here: (<5 psi at 6000 RPM)

Mine isn't too bad. Full RB from header to exhaust tip, the resonated version mid-pipe. No carpets or sound deadening though. Carpet will soon go back in, so it will be more livable.

Just tried out the phone app. 93dbA at idle from the driver's seat windows down.

I have one small round Magnaflow muffer (14" iirc), 3" exhaust. I can't hear my engine if I'm beside my friend's skyline though, so I don't feel too bad.
