I have a 97 f150 4x4 supercab, Im looking to do a custom 2.75" exhaust with dual rear exit, magnaflow muffler, magnaflow high-flow cats and LT headers. Im looking at the obx kit and stage 8 bolts, are they any good, any problems? How much power will I make doing this?

 

Not sure on the kit, but OBX is a much respected brand. LTs will gain you 20 - 30 hp and 25 - 35lbs of torque on average, with the dual exhaust to match it.

 

yea OBX are good man, stage 8 bolts are the way to go

good call on the maggie hi flows got a couple 94106 on mine and love the sound
