Just took some videos of my recently installed Mac mufflers (to go along with catted Prochamber).

Compare the above to my videos of the Borla Stingers below (again with the catted Prochamber):

Haven't had time to really compare these videos, but they sound pretty similar. In person, I think I have to give the edge to the Macs. The swarms of Borla fans on here may disagree, but my initial impressions are that the Macs just sound deeper and meaner. They are louder though and drone a lot worse.

I like them both, but I still like the Borlas better. How bad is the drone with the Prochamber? I want mine louder but I'm afaird if the drone in the car gets any louder I won't beable to hear myself think.

The Prochamber definitely made the drone worse, and made the car a lot louder, even with the cats.

They both sound good, however I think the MACs sound a little deeper. JMHO.
I may be biased though as I got a set going in this week
They both give the stang that classic american muscle sound.

I can't tell the defferance they sound the same to me.

I already have the axlebacks and was looking to put on a catted prochamber as well. Any chance you could do a startup, idle, and rev video? Thanks!
