Recommended supercharger setup?

Everyone gets quoted but me?? lol
In all seriousness, I am a big fan of GTM and their products, always have been. I have first hand experienced Stillen's Customer service, and their kit on my friends HR 350z. He has not had any problems with the kit, so far, but when we took a trip down to Stillen's facility to pick up the CARB sticker they would not give it to him because he was suppose to get his car tuned with the stock cats to be able to get the sticker. They never informed him of this and i now that for a fact because i was there before he got the install, after he picked the car up from the install, and the third time we were there to pick up the sticker. The only reason why he went with Stillen is because he lives in Los Angeles and cops crack down on street cars hard and he just didn't want to be hassled without a carb sticker at least. I know a sticker won't help all the time, but hey who knows. The other reason was because the kit is warrentied. I don't even know if they will honor that now because of the whole exhaust issue. I am not bashing Stillen, there are a bunch of good guys over there that have done alot of R&D work for our cars, which i am thankful for. So basically what im trying to say goes along with what others have said. The stillen kit is a quality system out the box, but if you plan on really pushing it, you could come across some problems and the customer service isn't the greatest. In my opinion i would go with GTM, as what i will be doing in the future. Not their supercharger kit, but their twin turbo kit. I have respect for both companies but I would go with GTM. Hope this helps OP
