weeee I finally got my headers , and me and my friend installed it today and the car is sounding really good. The installation was easy for the most part but we encounter a few problems.

first problem the headers didn't reach to the cat converter, so that took alot of pulling to make the exhaust reach the headers about 3 inches
.
2nd problem was mounting the 02 sensor wich will be fix tomorrow, once I get my muffler I'm getting my catback custom make at a local shop for $125, it's going to be 2.5 inch. hopefully I will have the money to get my catback done

I've heard that 2.25 is the best for the 7a and 5s. Post pics in your info for all to see man.

At 2.2L and 130-135 HP, 2.25" is about the maximum you want to run.

And one point -- unless you've managed to wedge a six-cylinder into your engine bay, which is actually possible -- you are running a HEADER, singular.

What brand did you get? And how much?

the headers were from ebay I paid 200 for them

what kind were they??

IT was A header...

calm down there buddy

A little correction never hurt anyone, I think people sound like idiots when they say they are putting headerS on a 4 cylinder engine, it makes it sound like they don't know what they are talking about and doing it just for show, not for gains. If it is all one piece it is *A* header. Multiples like on v6's and above are header*s*.

ooops my bad I'm used to saying headers because my other car is a v6 and for that one is headers. "header or headers same diffrence" you get the point

I finally fix the o2 sensor in the header, but my engine light keep coming on anyone had the same problem when installing header in the celica. how can it be fix???

Because you now have removed one of your cats...

did u put a corolla 02 sensor in the header that should fix it.

I left the stock o2 sensor in there, but the light kept coming on, I just did the catback and I took the other o2 sensor, now the ses light will never go off , but the car is sounding good now I also took the rear resonator off

can u post a link to the ebay header you ordered?

Because your car is OBD2, the computer can tell from the O2 readings that the pre-cat is gone. I'm nearly 100% sure that's the case.

the 7afe doesnt have two cat just one the 5sfe has two so thats not the prblem.now did u put the corolla sensor in or not

depends on the year.. therer were 2 manifolds avil.. i have both laying around, one hase a huge cat and the other goes manifold right to a 2bolt flange

ok point well taken but he has a 96 so he shouldnt have 2 cats so therefore the exaust mianifold shouldnt be his problem its that stupid 02 sensor it doesnt go all the way in i had the exact same problem he is having

I think the simplest solution would be, did he clear that check engine light after he putt he O2 sensor in.
