Has anyone used them mbrp exhaust on the 2013 and back 6.2 sierra denali's? The videos I'm seeing and hearing sound good, but that's video. I want to have a deep exhaust note at idle, good sound driving down the road, sound good when getting on it without sounding obnoxious or deafening. Without the done too or little as possible. Is this what you guys are getting with this system? Thanks in advance.
