: Do i need filter with tuner and exhaust ? Jason_2500 03-11-2011, 09:42 PM Like a Cold air intake? or the DPF? You need neither. TommJr 03-11-2011, 10:40 PM You really don't need any thing else. I know that banks will have an air kit soon, but as to needing it, I don't think so. I also don't think you need exhaust, being that the factory is 4" already. | ||
