I will start off by saying the guys at Cattman are awesome, I just wanted to know if anybody had any input as far as power gains before I pull the trigger on a bunch of cattman stuff tomorrow.

Here goes:

I am planning on ordering the headers + y pipe. What gains will I see with headers + y pipe, over just adding the Y pipe and eliminating the Pre-Cats?

I have seen a bunch of stuff about O2 simulators that I dont really understand. What O2 Simulators would be best and how exactly do they work.

One last thing! I have heard I may need a fuel management piggyback because most max's run rich w/ headers. Is this essential to the cars fuel economy and driveability or is it something that can wait. Also, what piggyback is generally reccomended?

Thanks!

It can wait, but you won't see all of the gains until you tune.
