If your saving to buy a Borla then I would just wait till you can afford the Borla, but as a more affordable alternative the Magnaflow is all stainless and built very well. I also like the way it sounds (though I've only used it on 4th gen LS1 cars) and if you look around you can get it new for around $380 or so. Here's Magnaflows page on 3rd gen cat back #16829
