Does anyone offer a header for a sb2.2 motor in a thirdgen?

I have the stahl 1-7/8 primary 3-1/2 collector with sub flanges on my 23* set up now. Real nice piece but need to sell them and get some much bigger headers with the right flanges.

 

Call lemons or a custom builder...theyll make anything. Downside is the $12-1400 price tag.

 

Will 4th gen headers not work?? I have no idea if you could modify a set?

 

Yeah if it gets that pricey ill have a chassis shop build some stainless fender exit headers. If I can sell mine it will help offset the expense some.

Not sure on the 4th gen stuff

 

What's the rules of that super street class?
