I like my Borla with the perforated cone in the tip...

But I also like the way other members VX's sound with flowmasters & duals...a much lower rumble than the Borla, way more agressive sounding at idle.

For side by side comparison, nothing beats a trip to Moab...

You should be able to hear quite a variety of combinations there.
