Hate having awd all the time wondering if its even possible to change it to 4wd to 2wd. Like in a blazer. Reading on other forums people do it with astro vans almost the same thing. So if i were able to do it what will all need? Also wanting to put flowmaster on it wondering if i could do center in dual out to 45 degree bend, what size the piping would need to be. Please help!!!
