This thread will be used to document in-cabin sound levels (Decibels) of exhaust setups.
We will use the android app "Sound Meter" found here: SOUND METER APP
I did not use the calibrate function of the app and please see app manual for phones that cannot register past 80db's.
All sound levels taken from window phone mount in center of dash over dash clock.
Please post your results following my example..
Current exhaust config:
Stock O2 housing
Ebay 2.5" to 3" downpipe
Mil spec 3" race cat
generic 3" exhaust
Magnaflow oval muffler
Sound levels with windows closed all sounds (Radio,blower, etc) off.
Car off in quiet driveway = 30db
Idling = 60db
Cruising at 70mph = 75db
3rd gear WOT = ~82db
PLease post your data
While I know these will not be absolutely accurate, I believe we will get a relative comparison...maybe better than listening to youtube video's
