Exhaust Headers, Which one produces best performance? Options

[ILoveMySilly97]

I have a 1997 Toyota Celica GT with the stock engine. All I have is a Short Ram Injen Intake and I'm thinking about getting some headers for it but I don't know which one will give me the best performance and best durability. I want a direct bolt on if possible. My exhaust system is bone stock. I noticed some members have the ebay ones but are they legit? Most of the ones I've seen online are all the same design? I found this "KO-Speed" one from eBay for a little over 100 after shipping and taxes. Yes I know I live in Cali and it'll not pass smog but I have the stock one just in case. Lol. Any good?

They're pretty much all the same for the 5S. Yes you will only gain 1-3 hp but you will lose just as much, if not more in ft/lbs of low end torque. I wouldn't waste your time or money on a high flow exhaust manifold (lets just call a "header" what it is lol). The only reason for one, for performance at least, would be if you completely built the head (high lift cams, lighter valves, angled valve job, full port & polish of the head and intake) Then the "header" would be beneficial. On a stock head, it's really just for looks or to complete a full high flow exhaust (which again, added to a stock system is more for looks and/or sound than performance.) Some may claim to notice more power, but after over a decade of doing this, I'm a firm believer it's just a placebo effect ... Like when I swear my car is snappier with a full tank of gas lol.
