How would this be different than x-pipe?
It has been beaten to death that a 3" catback will support all the flow needed for big horsepower. The problem with xpipe setups is that they dont exit out the rear.
What exactly are the benefits of an xpipe setup?
And how would the setup on the bottom be any different than the one up top?
The bottom one is the exhaust pipe cut down the center with a divider welded into it to separate the gases. How is this any different? Which one would perform better?
