I bought the car with the setup that's on it. Looks kinda homemade to me after the ORY but I think the exhaust on ls cars are weird anyway. So I don't guess I know what to look for as far as a good merge is concerned

It is. They have the Flowmaster merge Y pipe which is great. But Mufflex uses 3 different mufflers. A Flowmaster which is from what I understand also pretty bad, a Magnaflow which is just a straight through muffler which is great, and the Spintech mufflers which are crap. I remember a few years back I got in an argument with a friend about this and was able to pull up multiple threads about losing double digit horsepower/2 tenths+ at the track
