I looked at a `97 2500 5.9 extra cab with a plow today but it needs an exhaust system and a few other minor things.I`m wondering what is out there for aftermarket exhaust systems and what kind of money.Anyone have any experience with any certain brand,Flomaster,Dynomax.....?Cat back or full system?I`d like something with a little rumble but not too obnoxiuos-I`ll save that for the `cuda!
