It all depends. It is a highly debated topic amongst the G35 community. It seems like most people are going Borla, but I know that our sponsor BRM has a really nice exhaust that I plan to go with sometime in the future (maybe later this year or sometime next spring). Hp gains are still really up in the air right now for most. It mostly seems that they are all within a few hp of each other at peak on the dyno. The sound depends on what you are looking for. I've heard a G with Greddy straightpipes that is pretty loud, the borla is pretty deep sounding. The BRM and Nismo should sound a little louder than the stock but I'm not sure of the real differences. The stock exhaust is really quite good and sounds really nice as is, but you gain get some minor improvements in hp and sound by going aftermarket. I'm not yet convinced that the exhaust is worth the money unless you are changing some other things, such as headers.
Oh, and by the way, get the coupe. Nothing against the sedan, but you got to go with the coupe in my opinion.
