Mufflers?

Does anybody know of a muffler that will work on Zoomies? We tried some for a boat and they looked like morters at half track. We have to have some type to run OutLaw street.

The combo is a low compresion TA\FC hemi. (9 to 1, 526 brad head Hemi, 2 speed linco and a corwler glide. It is in a 2800 lbs 1984 Chrysler Imperal on Hoosier 22x36 street tires. We have been 6.60's on a fat tune-up. Also how much do you think we will have to change the tune-up (Fatter or Leaner?)

Thanks
Bob

 

Your EGT's will automaticly drop when you put Mufflers on. We had to lean ours out about .7 of a gallon from where it was with the zoomies.
