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.
 
I have had them on both my 318 and my 340 Darts. The ones on my 318 finally got a rust hole in one of them after more than 20 years! I called jegs and got the same mufflers again! I like the quality and volume of sound. I spent a pile putting Flow masters on my 340 a few years ago and don't like the sound as well. I'd rather have the Dynamax turbos back at a fraction of the cost...
 
It's hard to predict the best settings. But jetting up 2, and if that is worse, try down 2 numbers from what you have, should help you "feel" if it helps restore the power you had before. Although the track would be best.

I went to 36 on the timing and down 5 jet sizes and it's getting close. 40 mph in third gear it will break the M/T ET's loose.
