My Long Tube header build - Toyota Yaris Forums

xnamerxx · 11-11-2012, 12:58 AM

Most of the cheapies use 1.5" tubing which is way way to large for this engine so you'll end up with a huge loss of torque and a powerband that's to high up. I initially thought of that but the material cost of the header isn't all that expensive and buying SS to modify that thing isn't worth it.

I'm building it out of regular carbon steel even making the flange myself and all in it should be less than 300 dollars for metal plus the 3-4 hours its going to take me to weld everything up.

I'm actually working on a 4-2-1 header, so I can make it small enough to fit before the second cat.
