ok... i have decided on the SLP headers over the TES because of the stainless steel and the 1 3/4 size, i have the dual cat setup on my formula, will there be any cutting of welding required? i want to do this myself and a i cant do those things. how hard is it to re-install all the AIR stuff? headers are definatly my next mod, im just trying to get as much info as possible before i drop around 500 bucks on these things.

Yes, there will be some cutting and some welding. When I got my headers, they sent clamps with the pipes that connect to the cats. I wouldn't even bother with themn unless your going to use them just to get to the muffler shop to get them welded. If you can get a hacksaw, doing it the hard way, you can cut the exhaust your self. You only need to cut the y-pipe in 2 places and they are right on the welds. As for putting the AIR crap back on, no problem at all. If you got the install kit, it comes with rubber hoses, clamps, ties, bolts, and etc. It will make it much easier.

Just some advice though, take your time. It might look overwelming but if you plan out what your doing it will fly by. Don't try to rush it. If you cant do something, set it aside and try some thing else. The whole task will take a weekend, that's also after pounding down cold ones while during the install. Just kidding. If you need any thing else just let us know. Good Luck!

so, if i want to, i could intall the headers, then drive to the muffler shop with open headers and have it conected there?

another thing, about header gaskets. is there some better type of header gasket i can get to prevent having to change them. Also will i need a certain type of spark plug wire to get around the headers, and is there some sort of wire lume that will help.. thanks!

If you get SLP headers, spend the extra $$$ and get the install kit. The gaskets that came with it have been working fine since I had mine installed.
You will need 90 degree spark plug wires in order to avoid burning. Ask around for some wire looms, but wire ties in strategic locations work just fine

Yeah, just get them, they are the best.

thanks guys i will probably end up ordering the headers in june, man my car will be loud!

If you dont get the install kit, youll ned header bolts with an allen key cut into the head because it's too tight for a socket or wrench. I'd recomend the install kit, especially considering you are retaining the AIR system.
The headers are awsome, I bought mine from the factory fire, so they were covered with crap, so I sandblasted and polished them, and now they look awsome, plus stainless turns purple and other colrs when they get hot, really cool.

im definatley getting the install kit

I'm not sure but Z-Racing was doing a GP on them. I got 1 5/8 SLP for dual cats with JetHot coating on Y-pipe and headers + install kit(no AIR) shipped for $620.

Has anybody else seen the bad welding job inside one of the exhuast ports?

Search this board, the link was just posted to the GP.

And yes, some of the welding is bad, but its nothing compared to Edelcrock's bad welding!
