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.

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.

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.

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... |

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.

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?

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...
