From what you're talking about removing, why not just drop the k frame install everything and lower car onto the k frame like the factory did? It would be a hell of a lot easier the factory way, just sayin. Otherwise it's install everything then from the bottom install the headers. Oh and...
Your two off shelf choices are Doug's headers and TTi. You can get a custom set made or go for a set of stainless steel header ($$$). If your motor makes 550 or less Doug's be fine, 550 or more get the TTi.
Lol. Nah nothing like that but when you put the stainless stain headers against the Doug's/TTi, both Doug's and TTi seem soooooo much more of a bargin.
1. Those are stainless steel headers.
2. Just showing another option.
3. Which isn't directed towards you but just general, people should stop bitching about the price of Doug's/TTi, you could always buy a set of these just saying.
If you're after something like that, do a quick search for the mufflers for an 05 (or newer) Z06 Corvette. You're more or less after that switch on them.
