I don't know if they changed material in later years but I know my bolts and flanges had rust on them, and I'd bet a tbone a magnet would stick(yes I know 430 ss still has some iron in it) mainly just a lil more noise, I've had borla on a 300 I-6 ford that sounded pretty pretty pretty cool. My cousin also had a Tahoe with headers and borla on it and it sounds great aswell
Economy or power gains....eh I don't know, I smile more when I drive it I guess?
Unlikely materials changed. I believe it is stainless but likely not top quality. I can tell you though, my neighbors 2005 T4R still has the stock exhaust on it and he's got 230K miles on it. It does have 1 crack in the y pipe and the tail pipe broke away from the muffler but it was clean enough for me to butt weld it back up. Not bad for MD and VA winters and roads if you ask me.
Any chance you have a video of your exhaust you can post? I would also love to see a picture of the muffler they provide with the kit and if it's not too much trouble, maybe a measurement of the length of the body of the muffler? I appreciate all your help and info so far.
