Default Exhaust or PI Swap??

As it is almost Feb I am going to shortly be getting my tax refund and a few extra dollars I ran into thanks to Uncle Sam! I have been reading up on doing a PI swap. I know it is essential to gain power out of my 1997 GT with bolt-ons. I also have been looking into doing a header and mid-pipe install. I have both of these options priced and can afford one here at the end of the month. My question is which would you guys suggest doing first? Would it be better to do the PI swap and wait to get the headers and mid-pipe or do the Headers and mid-pipe and then wait to do the PI swap? Any input would be great thanks!

Save the money when you can do both.. It'll make it easier to to do LT headers while the heads are out of the car.

He's right.

But, if you aren't going to save/wait, do your PI Swap-no question about it.

pi swap hands down buddy, i would love to do the whole swap, but my intake "blew" on me, and all i could afford was just the intake (ok and tb and plenum), but def go with the swap if you have the time/money

Do the swap and try to do the LT's if you can at the same time
