They will last but mine have started to show signs of rust after 2 years,mine is parked in a garage under a cover in the winter and I only drive it in nice weather,I don't know how winters are where you live but I know in northern ohio there bad,with all the salt that gets put down around here having you car parked out side is just doomed for rust,I had a 94 gt parked at my old place ,it was 200 feet from the street on a concrete and under a cover,by spring my polished cobra rs were pitted pretty bad,even last year my buddys ta was left outside at his dads house out in the country and when he went to go pick it up his new 17x11 zr1s also were pitted,and the body damage that was on it rusted pretty bad,but I'm sure your winters aren't as bad ,I tell ya though when I replace my headers its gonna be tough for me not to get those ebay headers,a guy I know has them and they installed easy,still look great and he paid 200 shipped to his door,pacesetters are great for the money,I even put the crap gaskets in and they have lasted for 2 years lol,I will change those when I do the heads though this winter,have you installed them yet,just be sure to have a grinder handy you will more than likely have to make a small notch for the driver side header get in there
