I've narrowed my muffler search to either of these;
Steel oval Ultra Flo 17560 20" shell 25" overall. $86
or
Stainless oval Ultra Flo 17288 20" shell 25"overall. $148
According to the Walker site the Stainless mufflers rated "street" are quieter compared to the Steel units rated "sport".
I wonder if the difference in sound justifies the difference in price?
Damn, am I having fun picking mufflers!

And Jim Hands book makes it so enjoyable!!
