I have a 99 GMC Sierra, and have been through 3 setups myself.
1st was a 14" Magnaflow, then the large SUV Magnaflow, and now I have a large 3" in dual 2.5" out DynoMax.
All of them had interior drone.
My exhaust is dumped behind the passenger side rear wheel. I read in this post that dumping the exhaust behind the wheels makes the drone worse. Is this correct?
Will adding a bullit muffler in front of the main muffler decrease the drone?

I have been calling several muffler shops and they all tell me the same thing as "8MC" said the Flo Pro is the best for eleminating the drone but the 2504 will make it louder but will still not have that drone in the cab. They also said that on that motor you should either dupm it out the corners of the be or straight under the bumper.
I am going to try in the next few weeks. I will let everyone know how it works out for me. Hopefully I ma not wasting more money

Corsa would get rid of the resonance for sure. The HD has the same issue as the SS Silverado. The resonance is caused by the size of the pipe for the most part as well as muffler design.
