Your stock cat is HUGE and is retricted. By swaping it with a High flow it will allow your car to flow better. You will notice better response but not much. Do you have to pass emissions where you live? By running a straight pipe you again, prob won't notice a difference besides your car smelling like crap. Plus if the cops should pull you over you will get a nice ticket!

Well bro if your cat is clogged and it indeed has that many miles on it then you will def notice a change with how your car runs. If your opti is bad then you need to take care of that too. I put a Magnaflow cat on mine cause I have to pass the sniffer to. No cat means no passing the sniffer so I wouldn't be installing a straight pipe!!
