DC Sports Header install and evaluation

[cali yaris]

The stock header also pinches the tubes right before the collector -- totally restrictive.

heard most aftermarket headers make you lose torque and minimal gains at high rpms.

I made 15 whp increase (on the dyno) from intake, header, pulleys and axle-back exhaust. Peterpoop, I think you are incorrect that the header didn't account for any of that gain.

I never stated that the header doesn't give gains at higher rpms or gains at lower. I just said that I "heard" that's what most headers do.

Too many other mods involved with that dyno.

I'd like to see a bone stock yaris with a dc header and the dyno # it puts down oppossed to the stock header. And not a dyno that DC provides.



*If I decide to put the turbo on hold I'll definately go with Richard's setup.
