I am looking to buy a new exhaust for my Colorado, Magnaflow has two, one is a one in one out side exit 2.5" piping. The other is 2.5" dual exhaust and from diagrams I have seen it seems close to a true dual. My question is if ya’ll could help which would give me the best power increase and sound? Thanks.

You’re not gonna get much from an exhaust, and you have an I5 yes? it will never really be “true dual”

Whatever you do make sure you keep your EGR so you don’t lose gas mileage 😛
