Okay so I have a 4.0L in my '97 Ranger and recently shortened my tail pipe and put a cherry bomb glasspack. I'm looking to do a little more. I want to take off the back to back cats and put one magnaflow hi-flow cat on. I think this is a good idea. And while I am doing that I would like to replace my headers. I'm looking for some hi-flow headers but not sure what I should get. Any ideas on my whole exhaust plan or some good headers?
