dyno-max mufflers good / bad?

Im going to have to say I found them to loud at idle and around town. I installed a full TTI system from the manifolds back to bumper on my 68 Barracuda fastback they buzzed the interior and drove me nuts. I actually posted asking for quiet options. I am just to old at 53 and don't want the loudness for my street car. I get plenty of loud off my drag car. I know Im in the minority so if I were 25 years younger they would have been fine.
