Toluene Dart - '73 swinger

So... I went to cars and coffee today. All good fun, not a lot of people. I go to leave and get down the street, I get on it next to a pack of subaru's.. and sure as ****.. my damn muffler flies right the eff off the pipe. I'm sure I scared that suby kid pretty good when that sucker went straight pipe. That will be the last time I use exhaust clamps.
I went and bought some Dynomax UltraFlo's and welded them sumbitches on. They don't really sound all that great at idle to me, but they do sound much much better when driving and getting on it. But the idle thing could be because this thing seems waaay under cammed.

Sounds bitchin' , to me.... ! (Witch muffler, you choose? .. My turn down short system, is whizzing off ,the two cop neighbor's... You might need to check: primary float level, and pump shot... That slight hesitation,..... (Yeah , I am a butt head, it sounds SO GOOD , otherwise...)
