Are you talking about in cabin noise and drone? If so, that's good news. My friend's Tahoe had zero in cabin noise or drone. Which is actually much better than my vortex. That's really the only complaint I've ever had about that system...
Bob, what is on my "new" AV?
I had a local shop put on a Flowmaster 40 and run duels over the axle, around the spare, and two straight out the back with big old stainless tips. Sounds great, looks great!
Here are some pictures of my install..
