I'm new to the site and to the TITAN world. I just got my Silver 08 Pro-4X last week and I can't stop smiling. I have been researching cold air kits and exhausts and can't decide. I would like any input that any of you may have on what the best setup for these two adds would be. I do have price constraints, but I can try to find deals to help save. Thanks in advance for any help / guidance.
