which is better, i heard that the second isn't as good cause the exhaust has to turn around 180* to exit. while the first just has to split and goes pretty straight. i have the first on my car and am thinking about upgrading, but im wondering if it flows better then the second, cause if it does then i'll just get a new muffler like mine but better flowing.

#1 exhaust enters right side, leaves through dual left pipes

#2 exhaust enters right side, and leaves through pipes and left and right.

I prefer #2, but #1 might give a better sound.

 

Yes the first one does flow better and is a better design, just as you said. When looking for a new muffler look at the flow figs.-CFM
