Dynomax catback exhaust - so how loud is it? Take a look!
 
I've been a lurker for awhile and only recently have I started to become active on the forum. It's time for me to contribute so here we go.

One of the questions I had about the new dynomax exhaust when I was in research mode was.....how loud is it? Since i had it installed yesterday i decided to do a quick DB check with a simple iPhone app. The first round of tests were 20 second snapshots. The vehicle is a 2012 grand cherokee with the v8 HEMI. The dynomax exhaust is the full catback system.....part number 39513....that was purchased from Amazon for $485.98 plus shipping.

The first test:
In the vehicle with the doors closed and engine off

Second test:
Doors shut and engine at idle

I'll post some other results soon but I'd love for someone with a stock exhaust to download the tool and run the numbers for comparison.


Stay tuned....

Thanks for the data but how about some video? A quality interior cruising video with/without drone and a drive by would be great :thumbup:
I'll download the app and get some stock measurements for you this weekend if someone doesn't beat me to it.

Here's stock idling for comparison. Similar app but with Android. http://img.tapatalk.com/d/12/10/13/8ytuhy9y.jpg
Looking forward to your videos later :thumbup:
