With the new 4.8 V-8 FlexFuel, what will a flowmaster/other system sound like?

I'm going from a 1997 GMC Yukon 5.7 and I don't want my new truck to sound like a V-6 with dual. Just curious if anyone has put dual on the 4.8FF and if it sounds decent.

Thanks!

 

Lots of people have before. Won't have the same growl/bite as the 5.7 but still sounds good. YouTube can be your friend here

 

Thank you kind sir!
