Those are cool Steve, I didn't know they offered turn outs for those 3 disks. you know I used the steel wool packing and wrapping tape twice but it won't last very long, at least not in the collector up front. I like the snuffed sound of the steel wool. I find it all over my back fenders because the pipes drape back at the car. I haven't used it again since then.I also use the Car Chemistry inserts on my 53 but I've got shorty glass packs on my Willys. They also make a very cool turn out tip with their insert installed.
