i am in desperate need of a new exhaust for my 98 stang. My original exhaust fell off at the collector and since emissions is good till may 12 i decided to leave it alone but now the headers have started to rust and whats left of the exhaust now makes an extremely annoying rattling noise so its time to replace it all. I was looking for suggestions on what type of headers and exhaust setup to go with. I would like to upgrade to either a cat-back dual exhaust or go true dual but i want to keep all of the sensors and cats on to pass emissions until its old enough to not have to go... any input on the decision between cat-back or true dual would help as well as brands for the headers and exhaust
