So it's early innings as I just replaced the original factory system on my WK Jeep GC Overland yesterday. I was able to get out for a decent test drive and was very impressed w my new Borla Exhaust. To be candid, my first impression was underwhelming. After driving it though I'm now very impressed! This new Borla Exhaust will not annoy or attract unwanted attention unless you want it to. It's civilized at idle but growls when you hit the gas. My Jeep is almost scary quick now w K & N air filter!

Great Sound without being annoying.

This is my second borla catback system. They are fairly easy to install. the hardest part maybe getting your old stuff out. I put this one on a 2010 Jeep Grand Cherokee with the 5.7 Hemi. Sounds Great with out being annoying. nice mild growl. Borla is a little more expensive than other systems, however, worth the money.
