Here are some pics of the prototype headers from Stainless Works. We will be getting the car back that these will be on in about 3 weeks or so. So expect dyno number within 4 weeks. There will be a few options on the kit, all of them very reasonable in my opinion. For those that don't know Stainless Works, they are a top notch company that has a great reputation.
They are a 2 piece design, with a slip on merge collector. The tube length was modeled to be optimal for the blown 5.4, and the flanges are port matched to the cylinder head.
Here are the options:
Option #1 will be no cats with pipes to go to stock muffler
$1999
Option # 2 will be same as #1 with a muffler replacement which will flow more, and weigh less than stock
Estimated at $2800-$3000
Option #3 will be cats with pipes from the headers to the cats, then cats out the back of the car
Estimated at $2700-$3000
Option 2 and 3 are just estimated prices since they have not been finished yet. These prices are right inline with what the same parts would be on a Mustang. You are not being hit with any exotic tax here.
