But why would the Y-Pipe have a single inlet? I thought (i may be wrong?) but doesn't the exhaust come out of the muffler as a singlet and then split at the y-pipe?
I guess I don't understand why a person would keep the "y" pipe at all. If your under the truck doing custom exhaust ,why not just cut off the "y", and go true duals?
Then put on a crossover pipe then back to the mufflers. JMO
Honestly I think if there was any major gains to be had from doing so, the aftermarket would have already been all over it. i had the exact same thought as you, but apperently the y-pipe works just fine. Dodge should have done a better design but the bean counters usually are to blame for these kinds of issues.
