View Full Version : installed the Ebay header

07-24-2009, 06:02 PM
I got tired waiting for my fabricator to get started on building my pipes for my turbo system, so i spent some pocket change and got the Ebay header. Install was very simple. i did have to loosen the alternator to get the header around that stud, but that was it. took me abot 30 minutes to install.






after a quick trip around the block

Now for review....This header was an excellent bang for the buck. Cost was about 110 after shipping. i can feel a huge difference in acceleration. Im on stock exhaust from the header back so the car is still very quiet. In fact, i dont hear much of a change in engine noise. But the Butt dyno says more power is there.

Now strap on a 2.5" exhaust from the resonator back. Powerband will really pick up with the header on. I have the same header, a weapon r secret weapon short ram, 2.5" piping from the resonator back. Keep in mind mine was a cali car so i now have no cat. WOOT!

looks nice !

Did you have to move your cat converter? If so where did you put it?

07-25-2009, 03:59 AM
The cat is part of the stock manifold..soo once you remove the stock mani the cat goes with it...and the ebay header replaces it..soo unless he put an aftermarket one on somewhere down the exhuast..he doesnt have a cat anymore

Looks good BTW :D totally jealous of your freshly built n cleaned engine :thefinger haha

Oh, I see lol, thanks. Dose anyone know where to get an after market one? Is there a relocation kit for it or something?

one thing i have noticed after a week, the car wants to lean WAAAAYY out when the engine is cold. i dont have the 2nd O2 sensor hooked up so im guessing thats why

i installed this recently and i also agree its a good bang for the buck. fit good minus the o2 sensor studs were a little bent, so i had to widen the holes on the sensor itself. gasket that goes into the front pipe was the wrong size, too but i just reused the old one haha. i have the pacesetter CBE on my car, and now it rattles a little at a certain RPM... nothing another resonator wont fix though!

08-01-2009, 04:18 PM
Yeah i can second that rattle with the Pacesetter cat-back after installing the ebay header ...especially on a cold exhuast...right around 2500-3500 it rattles like an annoying civic..but once it warms up it sounds nice and deep.. A aftermarket resonator helps reduce the rattle..but its still there even with a resonator on it..but I can handle it

Looks nice smaay. But i want to see the turbo project finished.

Btw where'd you find this? seems on ebay the only ones i can find now are $300+

There's one.

You don't need a relocation kit to re-introduce a cat into the system. The Celica has a long enough secondary straight pipe that any competent exhaust shop can cut and weld in another cat. If you look at a California Celica they came with two cats. Just find a universal oval cat with the appropriate capacity and it should fit nicely.

There's one.

That would be an MR2 one.

So im assuming that the bottom exhaust flange is different, cause of the exhaust layout on the MR2. From what ive seen, lately all of the Celica models of this header have been pulled. Waiting to hear from Smaay

Thanks galcobar.

I have no rattle in my exhaust at all, I ordered the pacesetter exhaust as well and they sent me the wrong one, being too short so i used the piping they sent me and i got another muffler from a friend who had one laying around and took it to an exhaust shop and had them weld it in for $60. That included the extra bit of piping i needed for the system to work and all the welds. It came out very nice and i can get you a video of idle and rpm climb if you would like. I must say that pacesetter exhaust sounded like crap (like a wasp in a beer can :thumbsdow )! Thats just my opinion anyway. Oh and as for the 2nd O2 sensor, even with both sensors in it will still through a CE light being as the ECU reads the effectiveness of the cat. yes i know this dam light is annoying but you get used to it and its well worth the gain.

We have two o2 sensors? I only have one on my car......hmm

08-05-2009, 08:58 AM
Wideband maybe?

08-05-2009, 10:26 AM
i was told as per my mechanic that it has a pre and post cat O2 sensor to record cat performance. thus when the cat is deleted/removed even if bother sensors are in proper placement it will still throw a CE light. I need to go pick up a repair manual for myself and see if i can find the proper name for these two sensors. I can get pictures for you apon request.

08-06-2009, 07:10 AM
I never had a post cat O2 on mine. Must be Cali spec or something.

08-06-2009, 07:54 AM
that is very possible. I havent looked into it much. I should be racing this weekend and ill let you guys know how the header does with straight line racing. I hope to start doing some touge here shortly as well.

08-10-2009, 10:05 PM
my header has 2 ports for O2 sensors at the end. i put both sensors in and im not getting any CEL.

the only CEL i have is for the fvcking EGR

08-15-2009, 10:23 PM
so was this direct bolt on after removing the cat? I could use a little more powa .....is there a difference for standard or automatic?

and is this the same?

08-15-2009, 10:50 PM
Yes its a direct bolt on...No there is no difference for standard or auto
and no thats not the same one

08-16-2009, 08:08 AM
yes the two o2 sensors are a CA emissions thing, i have both of mine tied into 1 sensor and no CE light.

this is the one you want

08-27-2009, 11:36 PM
Yes most newer cars or trucks made to be sold in cali have the before and after cat o2 sensors. Most people with a after market exaust go to a dummy sensor but I doubt they make them for celicas.

I tried changing to the ebay header that I bought but i hit a snag.Bolts are all rusted.The adapter on my socket wrench broke when i was on my 2nd bolt trying to get off the heat shield.I sprayed the bolts with wd40 10 mins prior and still had a hard time getting off the bolts.Any ideas?
