Default Exhaust System Idea(stainless Works Headers)

Well, it looks like I'm yanking the L98 motor for head gaskets, As i sit in the evenings the Stainless Works headers in the catalogs I have keep saying "buy me buy me buy me!!!". This long tube kit looks like it would open up a choked stock 3 cat system. I was thinking about this kit(950$), a straight pipe replacing the cat and a Corsa power pulse cat back. Would this be a good upgrade without doing anything else? It's a street only fun machine and cruiser. Would it be a worthwhile upgrade in the power department? the car(88 coupe 2.59 geared)is bone stock, front to back. I like the torque of the stock motor and don't want to lose it.

Adding FL headers with no cats or a hi-flow cat and good cat-back should net around 25-30chp gain on your '88.

Hi.
If you look at stainless headers do as a friend of mine he bought stainless steel headers and got them ceramic coated with the silver coat. Then you have solved a lot of problems. You never get rust and you decrease the temp in the engine room dramatically.
Coated normal steel headers will in the end rust as the ront part of the lower part will be sand blasted through driving and one will get some rust attacks that will in the end destroy the headers. The surface of coated headers will stay good for years and years especially with stainless steel. My headers (coated) have got these rust stains from this blasting as I told.
Good luck

And then you're all set too, for any future mods you might want to do. Although the stainless headers are not quite as cool running as coated ones, they are a bunch cooler than mild steel ones that are just painted. You should have no heat problems with them as they are. I performed tests and the stainless header's surface temps were over 100 degrees cooler than standard steel headers measured near the heads and at other points.
