Well i ordered some American Racing Headers Long tube headers and mid pipe a month or two ago. Went with the 1 3/4" primary tubes with 3" collector and no cats used new ARP header bolts to fasten the headers down with. These things are very nice perfect fit, easy to install and look awesome! I went ahead and did a EGR delete! Ive also got a set of brand new 07+ electric fans to install along with a harness and relays from ls1fans as soon as i get my black bear tune finished up. I purcased a EFI live autocal to do the tune. Added a k&n cold air intake to let her breath in some more air to!
So far with out a tune, ive notice the truck is much more responsive and revs alot quicker! The exhaust sounds really good now! especially with that corsa performance cat back kit on there! It really opened up the exhaust alot and lets that corsa muffler shine now! When doing the egr delete i got rid of the canister and lines completly so that mess isnt under the hood now! Here is a few pictures of the headers!
