DC Sports Header install and evaluation - Page 7 - Toyota Yaris Forums

aucorium · 09-08-2009, 03:41 AM

well this is definitly a very informative thread ... i have been reading most of the threads of all the headers available for the yaris , from the megan headers with the install issues of not being able to use the spring bolts , to weapon R headers , and it seems as if the DC sports header is the only one without any install issues. I was thinking of saving some bucks and rather getting a cheaper header like megan , weapon R , thunder etc , but i recon i'll save a little longer and get the DC sports , no mess , no fuss , can reuse every OEM part.

thanks for the info guys :-)

PS: going to do a custom complete local exhaust and doing a de-cat , so by the time i get the header its going to make a noticable difference.

Do you have an aftermarket mid-pipe? I'm planning on doing DC headers for sure along with afe intake, and nst cr-lite pulley.

I have the afe intake, Nst pulley kit, DC header that i installed on Monday, nitto mid pipe, thunder axle back. It's an awesome combo of parts

The header does lose some low end but makes up for it, car has more punch in the mid and top end, ass dyno can feel the difference.

did you notice a difference with the mid pipe and exhaust? i didnt do those, i think the header had the best gains, and i dont want the noise/attention of an an exhaust.

After a few hours in the trenches, I finally finished installing my DC header. I had some issue loosening the O2 sensor, but I got it off eventually, with a 4 ft pipe as a wrench extension... The thread was ruined about 60-70%, but I managed to mount it on the new header just fine, so I'm not going to get a new one for now.

Unfortunately, I couldn't fit the header onto the engine bracket with the stock bolt (as it's supposed to be) no matter what I tried - like loosening all bolts and trying the header tab bolt 1st.

I eventually improvised a thinner bolt and nut to fasten them together. I hope it holds. No problems with the donut (it came of easily) and the spring bolts worked fine as well.

I was also not able to get my torque wrench in there for the world... so I hand tightened all the bolts... Any thoughts/concerns on that?

Did anyone else experience similar fitment problems?

What is the recommended torque? You can hand tighten if you know the feel of a torque range.

It's 25 lb-ft. I don't know the feel of a torque range, I only know how it felt to loosen it, even though I don't think that means much. I have a very short ratchet (a bit longer than my fist) that I used for 4 out of the 5 bolts, so I can't apply much torque, therefore I pretty much tightened them as much as I could, given the short handle.

One of the bolts is right under one of the tubes, so I couldn't get the ratchet under there and used a regular 12 pt wrench. Quite amateurish

Headers are difficult to get at back there, that is for sure. did you access the project from the top or from the bottom? just curious.

25 is pretty light.

Well, both ways, some things I did from under the hood - such as getting the old header out and the new one in, others from under the car - such as loosening 3 of the 5 header bolts, plus the spring bolts on the exhaust.

That's what I thought as well, 25 is pretty light and the gasket is metal, not something softer that I could squeeze and rip by overtightening...

kngrsll · 09-20-2009, 07:16 PM

get a friend to help. i had one guy go from the top, i went from the bottom. it was MUCH easier.

that post could be taken totally out of context btw

LOL, I wasn't going to say it.

It's a good thing you covered yourself them.

hatchbackkid82 · 09-21-2009, 09:17 AM

With all the exhaust mods i have it's really not that loud, ,on the highway it isn't too bad if you don't step on it. Whe your outside the car though it is a lil loud, but no where near some other cars i.e. civic with test pipes. The mid pipe and exhaust will complement the header really well.

chongopants · 11-06-2009, 10:56 AM

has anyone had problems re-using the stock gaskets? I am just of the old school ways where you replace them when you open it up... but I come from old V8s so should i go hunt down another gasket for my engine?

cali yaris · 11-06-2009, 11:49 AM

Always best to throw on a new gasket -- better than having to do the job twice because you got a leak. You can definitetly re-use the donut from header to midpipe, though.

I reused the stock gasket and so far everything seems alright. How would I know if I had a leak? Is running idle enough to tell? I started it and sniffed around, listened, but it's all very quiet at idle, so I didn't hear anything...

Did you have to modify the front flange of the Nitto midpipe to fit on the DC Sports header? I'd get the midpipe, but there was a notice about modifying the front flange to fit aftermarket headers....
