Sound proofing installed....

[1995 Gold Ciera]

....didn't work very much. The muffler is still droning loudly going up hills at lower rpm's in second and third gear. I'm irritated that I added extra weight to the car with no resolve but oh well at least it quieted some of the squeaks lol.

I think my next move is to do what IsaacHayes suggested and add a bit of piping between the muffler and the tip.

Any other suggestions?
