2010 Exhaust Sound

[aarolar]

I got a chance to drive my dads 2010 ECSB and I noticed it has an awesome exhaust note from the factory. Not loud at all but a very sexy throaty growl under acceleration. Does anyone know how they achieve this I looked and it looks like the same old big cased factory muffler but the internal guts must be different?

Was it a 6.0? They sound amazing stock. 5.3 is almost silent.

I noticed this to when I drove my dads 07 silverado ltz

5.3 it's really surprising come to think of it the wifes' Infinity G35 is the same way so it must be possible I just need to find the right setup.

You know our 4.8 worktruck has a surprisingly deep tone for being factory... Kinda weird hmm

My friends 07 5.3l has a good sound from factory as well.

Actually my 03 6.0 sounded like a beast factory too
