How much resonating is normal from A/T flowmaster?

It's aDogs Life · 03-02-2008

I recently installed a single A/T flowmaster muffler on my 2006 V6. The outside sounds pretty good for a single but the inside seems to be quite loud or should I say louder than I expected. (I am used to loud exhaust I have owned a couple of harleys with very loud exhausts in the past). Maybe it's just that the stock muffler was that quiet?!?

They're loud alright. Much more so than stock. Mine tend to drone at about 2500 at half throttle. Other than that, no problems.

Almost all axlebacks will have some drone.

Mine has a heavy drone at about 80MPH on the highway. Once you get above that or run just shy of that, the drone is not as bad. The resonating is bad a certain RPMs. That one is about 2800 at 80MPH.
I have been told by many people that is completely normal for a-back FlowMasters.
