header design (UEL, EL) can change the tone an exhaust has, but in this case the only thing that would really change the sound of this car is overall pipe diameter and status of the catalytic converters. When the pipe diameters dont all match up together and bottle neck you get that ricey farting with helium in your butt sound, when you lose your cats you get a raspy tone and that sounds worse when you couple it with a exhaust with uneven pipe diameters. You should try and stick to the same diameter piping as much as possible to maintain a smoother flow.

That explains why so many hondas sound like crap Another question. Is anyone running this header with a nitto midpipe + axleback. I am afraid of dropping some torque due to lack of backpressure

if you don't mind spending the extra $100 then get the DC...

FYI, the yaris header is really tiny , the most you'd get out of it just a matter 1 or 2 hp gain perhaps from one brand to another ....

just my 0.2cent...
