Default Headers + Exhaust

For those of you that have done these mods, is there any pressing need for me to do both at the same time? I'm in Phoenix, and will have PPE install its headers. They can also install aftermarket exhaust. I'd prefer to do the headers first, and see how I like them, but am also amenable to having the exhaust done at the same time. Any thoughts? Thx!

Save labor and time. Just saying, it will be A LOT louder than stock, but I'm sure you know that.

I just recently had both done. I received my exhaust first so I installed it about 2-3 weeks before getting the headers installed. Was good in a sense because I adjusted to the loudness of just the exhaust and with the addition of the headers was a bit more so I wasn't too thrown off of the sound. Still not bad as the car interior dampens a lot of the sound.
PPE + JoeZ FTW!

I would get both at the same time. Thats when you can feel how much the car pulls than stock. Also the ISF is to quiet anyway. You need to let that V8 rumble come out.

Thanks for all the responses! It sounds like it'll be quite a bit louder than stock - how much noise are we talking? I personally think the IS-F is pretty quiet stock (seems quieter than my IS-350 w/ intake and exhaust).
