Intakes and exhausts aren't going to do anything. The only real way to get performance is to drop a Hemi in it :)
That's the first time I have heard it nets 3.25". I will have to check into that. I have been considering just the RC 2.5" spacer kit so I may just do that.
2010 JK Unlimited. Bought in October. Bone stock other than the floor mats, and the taking off all the stickers.
Get ready though, things are about to change in the next couple of months :)
