I am looking to purchase a set of headers to go on a 3800 SC series 2 engine swap going into my 87 GT. I want to have a header for each side and made of stainless and built to last. Does anyone know who can help me out?

i wouldn't be quick to use headers unless you're gonna use other mods. i think you're gonna lose low end torque with headers (while gaining high end HP) . i wish i would have tried the stock exhaust manifolds b4 using headers on mine.

Very interesting. I will run this by my mechanic. Thanks for the heads up.

Highly suggest the "pace setter" style headers (with the Y pipe). There is an ebay version that is very cheap and very good for fieros.

I looked on ebay but don't have any idea which one to get. I am doing the shopping for my mechanic.

I agree with nosrac. I bought speed dady for a bout $100
they are like the pacesetter. Only issue I had was the exhaust flange had to be notched back a bit to clear the head stud on one side not sure why just one and not all but that was it .

I like this guy but he isn't making them anymore. He does beautiful work. I'm just running into dead ends when I look for these.
Keep in mind, I'm the money man and not the mechanic behind this project so I don't know a lot of the details and I'm trying to take some of the load off my mechanic by doing the R and D.
Can I assume these mufflers have to be custom built for a 3800SC 87GT engine swap? HELP!

Not quite true, and greatly depends on the header design. This is more true for equal length long tubes, but not so much for shorties, for example. Way too many variables to make a general statement like that. Also, header is just a colloquial term for an exhaust manifold. A custom made header with the same size and design of a factory manifold will perform just about as well (slightly better), but make the engine bay look a whole lot better, especially with ceramic coating, for those who want to show their car.

Find a local performance shop that makes custom exhaust for track cars, show them the picture of the exhaust design you want, and see if they can make you an exhaust at a reasonable price.
