My OEM headers are leaking, at the ripe age of 13 years old. I'm a bit putt off by the additional cost of ceramic. I don't care about how things look under the hood or if the low cost headers turn blue after a week.
The weak point is the Y pipe. I've replaced everything behind the headers a few years ago with Magnaflow parts as I lucked out on a sale. I have no complaints about the muffler as I ran the truck for nearly a full month without one (OEM exhaust pipe before the muffler rusted off, so I just pulled the muffler off). The wait time was due to shipping problems..
Headers are on my to-get list, but it's hard to make a choice with all the options. I get 9mpg in town, as it is winter after all. JBA is fairly low cost, so I might just pick up a set of those, although I'd need a day when it's not -22C to install them.
