Brian...
Nice to talk to you again!
I'm sort of out of the sidepipe business these days-after I sold my original business, but I'm sure you can have someone make a set for you. Find a good streetrod shop (net or in person) find out if they have any tubular exhausts? I suspect your pipes are now getting a little burned out which may actually make them 'bark' a little louder than they used to!
Save the front four tubes of course AND the rear mounting tab that bolts to the frame and have them weld you a new and Milder sounding (
)center tube in place
