sorry, it's not for sale. i just posted this thread to show what the header looks like, since not that many people have it. I got mine from andysautosport.com. it's $255 plus shipping. then you have to get the Check Engine Light eliminator from fastscions.com so the computer doesn't throw codes and mess your engine up.

yea, i'll be sure to upload a video of it. i'm having the shop instal the header, Check Engine Light Eliminator, 2.25 inch mid-pipe, and a 2.25 inch high flow cat. so it should sound pretty gnarly with my injen c.a.i and custom cat-back exhaust with tenabe axle-back.

GOT IT INSTALLED TODAY! I can definitely feel the increase in acceleration in 1st, 2nd, and 3rd gear; and in 4th i can feel and increase in top end power. It sounds a lot deeper under acceleration, downright mean with the exhaust 
for some reason it's a lot quieter when idling though, maybe it's the increased exhaust flow.

The headers are now on fastscions, says gains are 12.1hp, 9.8 tq with only the header.

Are any special tools required to install this? Does it just bolt on to stock components?
Is this a DIY type deal or would I need to go to a shop?

are you comparing the xb2 to our little xd? headers can make that power, but not in our car. I would say 6hp tops headers alone. Our stock setup is already well designed so I highly doubt we're gonna see 12.

Hey, sorry for the terribly slow response. I've been busy getting more stuff done to the car and getting ready to move into my apartment and start UTI. I'll take a video in the next few days and post it right away. I doubt it makes 12hp, it feels more like 6. But like I said, it is really noticeable under hard acceleration in the first 3 gears. And it seems to give the car more passing power when I downshift to pass. It's definitely more free flowing than the stock header. But due to the position of the header, you'll need a lift and an air socket with some serious extensions to get to the bolts. But if you have those things, as well as a welding torch you can probably do it yourself. The next thing I'm getting done to the exhaust is replacing the s-pipe that has 2 cats in it with a catless 2 1/4" pipe.
