Also, I dont know where you are looking, but i doubt you can find a new full JIC Ti for 850. The one John and I have goes for like 1150 or so. It is damn light, but unless you are gonna put the rest ofthe car on a diet, its kinda pointless or just for show. I wouldnt buy it again...too much $$$$.
But much like everyone else said...most of these ehausts are all the same. Some sound a little different. The Apex'i has a nice low tone and the fijitsubo is even lower, but other than that they are pretty much the same
