Installing headers on 95 Celica GT Options

[6thcelestial]

I need to get advice on putting headers on my 95 GT. Never done this before, but guessing that it is a matter of just removing the old exhaust manifold , and reconnecting the new header up to the exhaust, and bolting it back in. Any advice would be greatly appreciated. I can't drop a lot of cash, but would like to get the best quality I can for the money. Any suggestions on brand, and who to order from would really help too. Also need to know if I need to do a lot of work under the car, or can most be done right under the hood. Thanks in advance.

in my case it really wasnt hard at all, at first even i was concerned on doing it on my own, so i paid 80 dollars for installation 1st time,

but now with my engine being removed and worked on so many times, i realized its not hard at all, in a scale of 1-10, i would call it 3,(about as hard/easy as replacing sparkplugs)

its pretty much bolt on.
i used ebay sure2win headers. about 115 if im not wrong.

Check out the info section there's a how-to on installing header on 7afe. And I figure the 5sfe wouldn't be much different from the 7afe. Its real easy you just need some stuff like wd-40 and let the engine cool and soak the nuts om the head to the exh. Mani. And then on the second piece soak the nuts with it and just work at it. I did my whole exhaust in a day. I removed my whole exhaust and rewelded new pipe in most spots and I put tip on to. Its easy if you have the resources available. Good luck modding your celi.

EDIT: as far as the underneath(idk if that's spelled right) or on top of car its about half and half. If you have car ramps they'll help a lot. But a floor jack and a couple jack stands will be ok.

Thanks for the info. Will check out the sure2win headers.

Thanks Matt. By the way how much hp do you really gain??

I went with the surewin header on ebay. It bolted right up and I've had it over 2 years now with no probs and no rust (although I did wrap it) and it sounds great with a full exhaust to the back. Definitely noticed upper end power gain but a loss in low end power a bit.

I also had to have the 2nd O2 sensor relocated to the back behind the cat in order to get the CEL to stop throwing an O2 sensor code. It's been working now for a year since I had it relocated.

Just installed mine on Saturday, I must say it was a pain in the friggin neck. Every bolt was rusted on, 2 of the studs came out of the engine, on the bottom end I discovered 1 bolt that was already busted off, 1 that wouldn't budge (had to be cut off) and 1 that screwed off with little pressure. Then I find out that 2 of the 3 gaskets that I got with my header were slightly too small, and had to be bent a bit to get them to fit. My header is from Bonehead on ebay, surewin is out, and I cant' get a reply from him on when they will be back in (was supposed to be 3 weeks ago).

Now that the header is on, I am pretty happy. Mainly I am happy that I succeeded and got it installed, I did not notice much gain (we will find out @ my next fillup if I got more mpg's). The sound is noticeable, and it seems like it is changing the more I drive it, maybe I will get a bit more gain as it "breaks in"?

Yeah, I think it'll sound better with more time. I noticed the gains in the upper end especially going from 60-75 for example. Also, I did have a high flow cat, perf. resonator, and perf. exhaust with mine at that time so it may have been a little different from your experience. Did you wrap your headers yet? They get extremely hot.

the only thing is use 6pt sockets if possible. you will have to remove the manifold cover, and whatever is blocking on the left side, i think I took out the alternator or the bracket somewhere there. use a good gasket, the bottom reconnects to your stock, reuse your sensor, you will lose the top cat and have none left if you don't have the second one under. just understand your low end torque will be noticeably lost.
