Just finished the installation and OMG it sounds badass! Very happy with the dual-stainless tips out the back and that crazy flowmaster sound is music to my ears.

I was a bit worried because of people freaking out about how loud it is during freeway speeds with the droning but I noticed nothing at all and with the windows roll-up it is just a cool barely noticable rumbling sound.

Highly recommend the 50series, I did a few fly by revs on this poor chump in his Silverado sitting at a stoplight
