I was going to do some more performance things soon and I just wanted to know what you guys thought. Would I gain more from the CAI, pulleys, and a random technology cat or the VB mod. I can get the VB mod done here in houston bc some guy here does those for maximas. Let me know what you guys think about it. Any info. is appreciated!!Thanks

 

since u have jwt, just get the upper cai pipe to have a hybrid intake. and as far as the cat goes, i just got the substrate cat from wsp, it's definitely better build quality than the random tech cat i had, imo. (i haven't installed it yet) if anything, you should get the VI, it's just a bit more than the 3 mods or right at the price and the gains people have been getting are awesome. btw, if you wanna reason to hold off on vb mod and get firmer shifts, just unplug your line pressure regulator for your transmission and you'll be very happy (just try to do it only when needed, cuz the shfits actually can get annoying, lol).

 

VB mod... if you drive you car hard you will eventually need it. You don't eventually need the other mods.

High flow cats don't do much. You'll be lucky if you even gain 1 HP. Hold off on the UDP, but if you have extra money left, get them. Get a ypipe for SURE if you don't have one already, best bang for the buck mod. Get a midpipe to have a hybrid setup and get the VB mod.
