I am trying to identify the mufflers on my 98 RKC. They appear to look a lot like the Rush mufflers. They are slash cut, have a baffle about 1.75 in. internal size. The baffels are wrapped with fiberglass and are held in with one screw on the bottom rear. There is no markings of any kind on them. Here are some pictures I tried to get.

 

My Bassani's look similar, what dia are they overall? Mine are 4"

 

Whoops forgot to put that in, they are 3.5 inches overall.

 

Rush, Jackpot, Wild Pigs and more........they all look the same. I have arrived at the conclusion that one manufacturer makes mufflers for a dozen different companies!

 

Look like wild pigs to me
