Seriously though the reason I chose the HKS over the Stillen is because the Stillen a heavier exhaust than the stock exhaust. HKS is 15 lbs lighter than stock!!!!

Maybe we're confusing two different applications here. The HKS is for the coupe, and the Stillen comparible exhaust has two separate mufflers. For the sedan,, the Stillen has one muffler and is listed as 13 lbs less than stock system.....
This is the power that I was talking about when I have my stillen trueDual on my car, but no one believed me 
... It just never stops pulling at above 3.5k rpm... (when compared to the stock exhaust)

Gotta tell you this thing is a head turner in such a good way. The power of this car is sooo smooth and the sound is IMO very nice. I think the HKS might be in some peoples taste with a sound that is a bit less refined in its exotic presence, giving it that raw straight pipe sound with less bass, but the Stillen has a deep roar that sets it apart making it sound like it has a more power.
I have definately noticed the power it produces throughout the power band. It accelerates with an engineered gracefulness that only Infiniti could produce and it is magnified so much with the extra juice. The 80-120mph range is just a joke, the needle doesn't slow a bit and just laughs at the digits as they fly by. High end on this would be a match for close to anything on the road and accelerating out of turns is just magical as before, it seemed it lacked just a bit when it got to the 3000 rpm range.
I would like to experience the HKS to give a true review of which I like better, but even the guys at Midas stopped what they were doing and came out to watch and listen to me start up my car and drive it away. The guy gave me the keys and said "you're gonna be hella happy with this exhaust" (ya I'm from Nor Cal).
I can't wait to get high flow cats and headers to unleash the full potential of the sexiness the engine has to offer.
BTW, STILLEN on the tips looks so sexy.

It really comes down to preference b/t the two.
