TTI exhaust too loud

Had the same issue with my Dart! I had Flowmasters on it and the drone effect took all the fun out of driving the car. Also had Magnaflows which sounded nice UNTIL you nailed it! Way loud! I ended up using Accurate Exhausts high flow mufflers and now it sounds closer to the Mopar original mufflers that came on the car which I always thought had a nice throaty sound. My Buddy has the TTI setup on his Dart with the Dynomax that came wiith the system and he is starting to complain more and more also about the resonance/drone effect at around 2000 - 2500 rpm range. His system is about 4 years old and it gets louder every year! He's now thinking of changing out his mufflers to something less noisy!
