Re: "BIG" truck forum C/40, C/50, C/60 and the like...
Talk about backfires sure brings back memories. With my 478, every once in a while when I was at a high speed and let the truck coast down towards an exit ramp in 5th High, it would let out a blast equal to an M-80. The first time it ever happened sure was an eye opener. It never split any mufflers though. Maybe because they were Straight-Thru Duals? I'm not sure.
