So you actually have one in your possession? Pics would be great and let us know how the install goes. I am thinking about getting these if the feedback of quality and install is good.

Cool, I have been on the verge of picking this up. Kinda waiting on a dyno printout. I want to make sure it doesn't loose power in other parts of the power band. Hey, when you get it could you post some pics of the product next to the stock manifold? Thanks man any info would be greatly appreciated!

DIY for weapon r header (do it at ur own risk i do not take responsible on any injury or burn)
please do let ur car cool off b4 work on it
warning !! b4 start make sure u have new 2 nuts (show on pic below) for the new header that connect to the cai because the old header nuts are welded on you cant reuse it also the o2 senor have a shield around it somehow you have to cut that shield out 2 take the senor out so make sure u have something to cut with
step 1
take out the red circle part
oops b4 go to step2 please unplug ur o2 senor is also behind the engine
step 2
take this shield out (behind the engine)
step 3 take out these 2 nuts
step 4 jack ur car up and take out the bolts on this part
step 5 take out the lower shield
step 6 take the 2 bolts out (when take these out be careful because it has spring on it wear safety glasses )
step 7 take this 3 nuts out
step 8 go back to the top and pull ur header out carefully (warning !!! remember unplug ur senor first b4 u pull)
step 9 after take your old header out u will see a round shield on the senor cut that out and unscrew it put it on ur new one also u will see a round gasket thing on the old header do not reuse because weapon r header come with it just snap the new one on ( below is the old round gasket i am talking about)
step 10 after u put on the senor and round gasket on the new header go back to the engine check the header gasket for any crack or damage ( not the round gasket i show u earlier is the one that go on the engine ) if everything look good then put it on after screw in all the nuts and bolts be sure plug ur senor back in
step 11 these are the parts that u will not need on the new header
