Thinking about upgrading the G5 exhaust. Not for sound but for flow. It has the 2.2 and I hear the LSJ exhaust is a good upgrade. The 07s received the header so I would only need the DP and Catback.

Stock 2.2 exhaust is 1 7/8"
Stock LSJ exhaust is 2 1/2"

I found this thread with a sound comparison and it doesn't sound drastically different.

I wouldn't waste money on it. What kind of gains do you expect? I assume exhaust will cost a few hundred bucks.

Nope, stock exhaust is always cheap, should be able to get the full catback for under a hundred, easily.

Gains? More or less looking to open up the back end, since the pipe is crush bent the stock gets tiny and chokes up. Once the intake and exhaust mods are done should easily net 2 mpg or 3, and maybe more if it ever gets tuned.

go with the stock LSJ. its a nice exhaust upgrade and it is not 2.5, its only 2.25 i believe, it might even be only 2"

I know it isn't 2" but I have also seen 2.25...

Either way its all good. I think it is 2.5 and at the crush bends its 2.25... The stock 2.2 gets under 1.5 at the bends.
