Rear Floor tells the tale.
I took the round cut outs from the top of the muffler and welded two bolts to make reinforcers for the new exhaust hangers.
Cad bolts are sub frame connectors.
tombstone aluminum is drive shaft safety loop.
The rusty looking stuff is mostly just carpet Jute.
Comments and Observations;
Now that I've wired it up enough to try em and drive em,
The exhaust has a pleasant burble and you can still talk over it in the car even when under load.
The exhaust is a little bit louder than was hoping for but not bad.
The cut out (exhaust leak) is more quite than i hoped for but still has decent death tone.
Remember this is all with cast iron manifolds and a two barrel carb still.
The 289 is defiantly more peppy now and wraps up lots quicker. She'll spin the tires further from a dead stop than before.
New exhaust also clears the usual speed bumps on the regular paths we drive.
It doesn't seem to have any of the flow master low/mid RPM drone which I was concerned about. (drone masters r famous for drone)
Now she sounds like a real V8 Mustang.
My sons friends were impressed, which is how teens judge stuff.
Now we're just waiting for the victory rev video.
Will be woking on that here directly.
