scion header interchange? - Toyota Yaris Forums

bladesmith6 · 07-14-2006, 11:53 AM

Does anyone know if the any of the 4-2-1 headers available for the XA or XB will fit on our configuration? I have the lift back and was thinking their is a chance since they are the same engine after all. Please chime in if anyone has looked into this or tried to test fit any of them.

I'm not sure if the O2 bungs are in the same places or not, but if that is not a problem, and there is nothing in the way, it should fit- you would need to have a custom exhaust fabricated, though.

HanSel · 07-14-2006, 05:06 PM

yea what he said

if it all fits and there is nothing in the way, they you might have to cut or extend the exhaust pipe so that it doesnt hide or stick out of the bumper..assuming the cars arent the same length.. im not sure.

Are the Scion guys really seeing worth while gains out of a different header?

Im guessing with intake, catback, etc., it that much more noticable, but what about just the header by itself?

HanSel · 07-14-2006, 06:23 PM

probably not. youd have to get the whole setup to feel a real difference, unless your butt dyno is really good.

from a catback, youd only gain like 3 or so hp..its not that noticeable.

Moose · 07-15-2006, 08:28 AM

With a decent I/H/E setup, you may see 8-10 hp to the wheels- maybe. Be prepared, though, for a loss of torque on the low end.

soros151 · 07-15-2006, 05:40 PM

You will see a lose of low end torque depending on the setup you have. If you go too big on the intake pipe or the exhaust pipe diameter, then you will see a loss of torque.

ChinoCharles · 07-17-2006, 12:25 PM

That kind of sucks. Torque is the thing this car lacks the most. Someone put individual throttle bodies on a Yaris and post a how-to. It would be the meanest n/a economy car on earth.

Snake · 07-17-2006, 02:27 PM

go with 2.25" piping and you wont see any loss of anything
just get rid of the 2 cat setup and install only 1 high flow cat with no resonators, just a muffler at the end of the setup to free up some hp
you will notice a big gain to aid with the header install

soros151 · 07-17-2006, 03:58 PM

I say about 6 to 10 hp on the Yaris.

NichO · 08-29-2006, 01:43 PM

SO..........

Does anyone know if SCION xB HEADERS fit a YARIS 06??
Has anyone tried it?

I've looked the engine bay but it seems that the headers are a bit to the passenger side comparing to a YARIS 2004 2NZ-FE (from CHILE)...

At least the 2NZ-FE and 1NZ-FE 2004 uses the exact same headers that Scion xB..

but a YARIS 2006??? are compatible?

THANKS!!

6-10 hp on a 106 hp car is an enormous gain. Keep in mind that that piping is small for a FI setup and if you planned on throwing a turbo/supercharger on later you would be doing your exhaust allllll over again to see proper gains. Something to think about before going and having an exhaust custom fabbed.

It will not, bolts up fine to the block but is not in proper line for the Yaris' exhaust.

THANKS FOR THAT INFO!

jmew0ng · 08-30-2006, 01:19 AM

Bummer the headers don't fit... I felt a gain in torque in the echo(w/ scion headers ebay non-brand) It definately felt like it picked up quicker. :x I had stock exhaust with AEM cold air.. HP Wise.. I guess it "appeared" to increase top speed by a little.. but judgement was based on this mild downhill empty freeway (still comparing downhill stock vs downhill with mods) Upped top speed by like 3 mph'ish not too sure.. i just know it almost touched 115

RossP · 08-30-2006, 06:16 AM

I know theres a header in development, cat back exhaust and lowering springs being developed by a US company atm
