Power Loss
My bonestock Pathy has about 200,000 miles on it. Maintenance has been regular oil changes and anything that has been needed, etc.. Primarily a daily driver so it does not see alot of hard miles. I just put a new Cat on it. How much does a cold air intake and thorley headers run? Does K&N make a cold air intake for Pathfinders? I'm not following on the worn rings!? Which rings would that be? I not the most mechanically inclined person I have to rely on my Dad's mechanic that does not speak very good English!! Would a new exhaust pipe help out? Thanks everyone..
