If I was you I would save up for the JBA headers, they aren't that much more and people on here swear by them.
Header installation questions
First of all, thank you for all of your posts. I have been reading threads here for a while. My truck is finally paid for and out of warranty, so it's time to play!
I plan to install a set of Pacesetter headers (yes, I'm on a budget) with no cats, Flowmaster 40 series, and dual echo tips exiting the rear, and a cold air intake soon. What else do I need to be concerned with?
Will I need to "tune" for A/F ratio concerns? For the secondary O2 sensors, I found a relatively cheap universal dual output sim. (Universal o2 simulator dual output [unv-o2sim2] - $40.00 : O2 Simulator, E-commerce) Will this work to remove on a Titan? If not, can someone give me advice on where to get a good deal. I don't care to solder resistors to make my on.
Thanks in advance for any help.

I believe they've found that the 3" collector on the Pacesetter's is too big for our Titan's. I remember a couple of guy's had them & ended up switching them out. If your on a budget, i'd just save up a little more & get some Stillen's, JBA's or DT's. You'll get much better performance! 
Thanks for the advice. Any ideas on if I will need to tune or flash my ECU or will adapt to headers and a cold air intake.
eah pacesetters and Flowmasters aren't great for performance. Anyway, its hard to say what will happen. You will probably be ok without a tune, but, sometimes the AFR can go crazy. Is your truck FFV? You could also get Stillen's emulators for the 02 sensors.
I can't help but notice everyone here loves Magnaflows and JBA or Stillen. Hard to argue with the masses. How will I know if it is running to lean after installation?
You will need either Uprev or a Bullydog GT. Magnaflow's are just good because they perform well. But also Borla's, Dynomax Bullet's, and Aerochambers, along with pretty much any muffler that is considered a "flow through" is preferred for performance. Flowmaster still has its following because it has a great sound
