Converting 318 to Dual Exhaust

I had to replace the rusted out mufflers on the Swinger I just bought. The last owner fashioned a dual exhaust by cutting the original Y pipe and adding to the other side. It's not too pretty but it is functional and with the new DynoMax Super Turbo mufflers it sounds pretty good for a stock 318. I used a #17730. Sometime today I can take a short video so you can hear them. tmm
