2000 GT, full length headers

[86pony]

I have just purchased a set of Mac full length headers for my 2000 GT..
current exhaust system is basically stock...
I am going to delete the cats as we do not have emmissions testing here, so that should not be an issue, i also have a predator tuner which will allow me to turn off the rear O2 sensors
What other parts do i need to get this all bolted together and working, and will parts from other manufacturers work between the headers and the rest of the exhaust system..

Thanks for any help..

It didn't come with everything you need to bolt it up?
Wouldn't mix and match unless you know it will work.

I have everything to bolt the headers to the motor, but since the current exhaust is basically stock, i will need something to go between the headers and the mufflers...Once i get the system removed from the mufflers forward, i will bolt the headers in, then see how much of the pipes from the muffler forward i can use, then just have a couple of pieces fabricated at the local shop, to join them to the headers.. It all sounds quite simple, but probably not...
I understand that Mac makes a pro chamber for this purpose, but i am trying to do this on a tight budget...I will let you know how it works out......

They sell h and x pipes for long tube headers.
