Yes. What you want to do is:

Unbolt the heat sheild from the stock header.
Unbolt the stock header at the top and bottom.
Unbolt the Stock header from the engine mount.
There are three places that it bolts onto.

nows the tricky part the dam header and heat sheild wont come out easy

Monuver the header around from the engine bay untill you can remove the top heat sheild

now repeat for bottom heat sheild

Now monuver the stock header around untill you can get it out. I found that if you can flip the header around it will come out easier. The damn Engine mount on it will make it difficult to remove.

Now just slide the DC Header in. It will be much easier to install because it has no Engine mount on it.

IF I were you I would also Thermo-Tech the Header before installing.

You can get the stuff at any Jeggs, and all you have to do is wet the stuff down and wrapp the header with it. Then you take the heat paint and spray the wrapping when its dry.

The stuff allows less heat to dissipate from the header. This means that the exhaust will travel through the header faster. Which is good.
