What can i do to improve my 3.8 in performance
If you're serious about doing header install I'd recommend these to go with...
- O2 Extension Harness #
ZZPerformance - Stainless Exhaust Clamps #ZZ-SECLMP
ZZPerformance - EGR Block Off Plate #
You will for sure need both block off plates if you delete EGR. And I would go with Two 2.5" clamps and Two 3" clamps because the clamps that come with Speed Daddy headers tend to crush the pipe which I didn't feel comfortable with. And the o2 extension is a must as well..

Sorry I'm not having any luck finding Speed Daddys on eBay anymore. I believe they may have stopped making them. Not sure why though.

^^These are almost identical though. They aren't Speed Daddys so I can't guarantee their fitment.

Honestly I'd probably go with these if you can afford them. They were a little out of my range at the time I was looking for headers so that's the only reason I didn't get them.

Shipping is not Free, that was a temporary promotion that ended March 1st. It was supposed to be taken off of the website in the description, I am fixing that right now. If you want to place an order email me and I can give you a promo code that will take $10 off, which is pretty much shipping. Thanks!!
i wouldnt bother buying the erg block off plates form zzp. just cut the tubes on each side of the erg and pull off the mounting tabs then use black rvt and a penny to seal the hole and bolt it back on the the lower intake and header. it costs .02 (assuming u have the rvt already) 
and it does work perfect, this is how i bolcked mine off on my turbo monte
