This week I added a SleeOffRoad rear bumper with ladder and spare tire assembly, an ARB Combo front bumper, OME 1.5" Lift kit, (2) Light Force Blitz 240 lights and a new Optima Battery. I am considering the K&N cold air intake and the stainless steel Borla exhaust. I have heard that the new K&N system is very noisy and the Borla exhaust sounds great, but performance is negligible. Anyone added these to their 100 series or know if it is worth the expense for these items? As always, your comments and knowledge is appreciated.
