On Vacation
Turbo Magazine - September 2002
Manufacturer Blitz
Type Nur-Spec Racing
Sound Decibel @ Idle 104 dB
Sound Decibel @ 3000 rpm 103 dB

...that looks odd, Turbo...

Never seen an exhaust that was quieter at 3000 than it was at idle and thats a rather high db for idle.


On Vacation
I am reading up on different installs of that exhaust. Some say they hit 127 db then put the catback back onto the center and it dropped to 105 db range.

Thats comparable to putting cherrybomb on for an exhaust or any glasspack or straight pipe.

Just to revive this for one detail that could be rather important for folks needing a comparison. Does anyone have information on stock db levels for the various years? I know I'm personally in need of the information for a 2011+ for comparison.
