Finally, just installed my Hotshot Headers and jesus! it is a bitch installing it! freakin heatshields are pain in the ass, its hard for me coz i only jack the car up and crawl under the car about 100x , you can pretty much install the headers yourself but best if you have a hydrolic lift. you gotta have someone to help you out during install, thanks to Ryan for the help. tip during installation is, you gotta have the right tools, make sure you have a 9 point 12 inch deep socket to take out the stock headers, patience is always the key to good installation, you will be workin from the top and bottom.
by the way, no need to take out the valve cover, you will have to cut a bracket so you can grab it from the top, there is no way you can take it out from the bottom.
the gain? yes i can feel it, better acceleration
and this DIY installation saved me 80 bucks!
if theres any questions, feel free to ask
