Re: 4.7 V8 Gibson Cat Back

Drone is an annyoing sound that resonates inside the jeep when driving. It usally occurs around 2000 rpm. One of the reasons i went with the gibson is because it has Zero drone.

Dave if possible take a shot underneath of the exhaust. I want to see if its different then mine.

Re: 4.7 V8 Gibson Cat Back

about to pull the trigger on mine, but in your opinion, is it loud only relative to the original, or loud relative to, say, a diesel truck

hmmm its def not louder than a diesel truck or even close lol

its louder than stock thats for sure... but after a few days of driving i think its a little more mild then when i first got it. Thats usually the case with these cat back systems, takes a little time to break in to get the true sound.


at first i thought the sound is too loud... almost sounds like a boat with a big ass motor going brum brum brum brum but its toned down a little... its starting to grow on me a lot... i really like it.

Re: 4.7 V8 Gibson Cat Back
