2000 Suburban 6.0L exhaust advice

[rbell219]

Hello all---I have done some research and reading on aftermarket exhaust for a 6.0L Suburban. The advice I get from various tech support calls (Flowmaster, Holley, etc) and even some muffler shops is that ANY aftermarket muffler whether dual out or single, creates an almost unbearable resonation in the cabin at low RPM's especially at 70-75 mph.

 

Now I've read some threads on here that suggest the opposite. I don't mind a little resonation--i like to hear my exhaust, but this is the family vehicle with kids so I don't want to drown out conversations and the radio on the highway.

 

So, what do you guys have on your 6.0L Suburbans or Tahoes? How is the inside noise level? For comparison's sake--my 5.7L Ext Cab has two Flowmaster 40's on a true dual (factory) system dumped right at the back of the mufflers---my wife hates it all together--inside and out. So I'm looking for something a little quieter outside and a LOT more quiet inside.

 

Thanks to all......
