DC Sports Header install and evaluation - Page 10 - Toyota Yaris Forums

4/20 NEVER FORGET · 12-03-2012, 08:39 PM

I have to defend the DC header, as I think it's been the single best bolt-on since I started messing with this car.

First mod was a K&N typhoon intake, other than more engine noise, I didn't feel much change.

Second mod was the DC header. I noticed no mid-range torque loss and a noticeable change to the way the top end acted. The engine breathed better in the top end, instead of running out of steam before redline like before. The power across the board seems more linear. Despite the cost I would recommend the header.

Last engine mod I've done is a resonator-back obx exhaust. I didn't really notice any seat of the pants change from this.

Now with these mods the car is easier to drive. It's surprising torquey in 5th gear, I don't have to downshift to 4th gear any more when going up hills on the highway, even with passengers. It still doesn't have the top end that my Honda cars had, which it probably never will. It pulls really well in the 3000-5500 range though for a 1.5L. Overall I'm happy with the mods, I/H/E are worth it in my opinion.

^ Good luck, and congrats on vacation time!

Do show us pics of your project, and jack up the front of the car. It makes getting to the headpipe bolts sooo much easier from the bottom.

I know this header is ceramic so there's no need to wrap it right?

xnamerxx · 12-09-2012, 10:56 PM

DO NOT WRAP A HEADER!!! wrap is bad avoid it, it holds moisture and increases corrosion. Its coated leave it as is.

DJYojimbo · 12-09-2012, 11:01 PM

Thank You for the advice

*tk-421* · 09-27-2013, 04:11 PM

Possible? Sure.
PITA? Definitely.

WeeYari · 09-27-2013, 05:23 PM

The flange bolts from header to downpipe are only accessible from below. I don't know about you, but personally I cannot fit under the car if not raised.

Neurotic Hapi Snak · 10-07-2013, 09:27 PM

Is there a reason you don't put the heat shield back on? You'd think you'd want to, to keep your engine bay cool and exhaust header hot.

catliektheif · 11-16-2013, 10:36 PM

I just installed mine yesterday and i LOVE it. it was a PITA to take out the stock header without a 12mm deep socket.. so if you are thinking of getting the dc header make sure to get one! I ended up going to the store to pick one up when i got to the last bolt.. lol. No CELs and no leaks! Definitely recommend it.

I have an afe short ram, trd axleback, MI pulley and I'm an AT. I definitely feel a difference and getting to 60-70mph is like butter.

TRD made a 4-1 header (exhaust manifold) for the Vitz 1NZ-FE.

Yup they did. Welcome to a 3 yr old thread.

SirDigby · 04-18-2017, 09:52 PM

yeah. it's not even useful information...

tarkus · 04-19-2017, 08:03 AM

OK, I would love to know if there are any other good headers out there which give similar low Rev improvements.

Weapon R is for low RPM gains
DC is for high RPM gains
Megan is....idk cheap?

This is true based on the 4-1 vs 4-2-1 design. However, I did notice the torque curve shifted left by about 500 rpm or so with the dc header. This made a difference in the low end still.

This is likely due to the fact that our headers are so short because of the rear exit design which doesn't make the headers act like tradditional long tube deigns

That said I've never used the weapon r header

So which gives better low end or high end?

I also see a number of Yaris sports headers on evilBay, and I wonder if they're any good or should be avoided.
