I don't know if this is the place to post this? I was wondering If anyone is running a gibson cat-back exhaust on there explorer. I wanted to know how good there are? Could you tell a differnece? I also wanted to know if anyone is making a split rear exhaust for a 98 explorer? Does the Gibson give a good sound? I have not been able to find anyone that makes a set of headers for a 98 either. Is it possible they don't make them? Any information would be appriciated.......Thanks for your help.
