2013 Jeep Grand Cherokee 5.7l hemi
I recommend this exhaust for people looking for a more aggressive tone, but not overly loud. When you're on the gas you can hear it, but when you are cruising you hear nothing. If you are looking for a more aggressive tone that's loud and that you can hear coming a mile away then this is not the exhaust system for you.
I did quite a bit of research before purchasing this exhaust. I had read about fitment issues and excessive drone or rattling with other brands. The Borla far exceeded my expectations. The sound is amazing... I have this paired with an aFe intake and the sound/performance are amazing! I do get slight drone around 1500-2000 rpms only in "ECO"mode, but not enough to bother me... and it isn't too often that I'm in ECO and my radio isn't loud enough to drown out the drone anyways. Great Exhaust!
