Found a fix for my annoying drone at 1600-1900 rpm..My exhaust system starts with 2.5 coated ram horns & Pypes system with X pipe followed by Dynomax turbo mufflers...Drone was stupid loud .especially going up hills.
Installed Car Chemistry inserts with the end caps..Worked sweet no more drone and still rumbles..No popping on deceleration anymore either ...Vette is more enjoyable to drive ! Alohas ....

I used those inserts on my car too. Have Borla mufflers, but they droned something horrible before installing the inserts and an x-pipe.
