I was looking at the hedman headers. I dont want air pipes but also am not shure if I have to have them where I'm moving to (northern arizona). other brands specify slip on cat or bolt on cat... so which one is the hedman? maybe I'll just junk the cat altogether. as long as its not to loud nobody is gonna care up here in wisconsin. so. after get the hedders and figure out what I'n going to do with the cat, I need to replace the rest of the system. should I just get stock? I want to maintain the dual hidden outlet, but I want a better muffler to fit in place of the stock ones. I hope somebody hear has some info they will be willing to share here and give me some ideas tia
