Topic: new Doug Thorley header with Flowmaster 40 video

So i got my DT header on, and i now love it

[ROCKO]

a header will not make that much power on a stock toyota motor (if its stock) you're going to have to upgrade the cam and a few other things to really fell the power

[zippo]

I have some stickers that add 10HP depending on where on the engine you place them!

Yeah a godo CAM with the header will really wake it up.

if you got 10 hp to the wheels from the header by its self, you would never feel it. So dont be so quick to say it did nothing. Its for this reason that lots of people think a 4cyl isn't worth messing with. And why some many poeple do a v6 swap. you also have to take in to account were in the RPM range the power is. 10ph dosn't mean 10 at every RPM. it may only be at 4000 that its that much and it could be that at 3500 its only a 5ph gain.
