Upright Headers

Is there any power gains in running upright headers over regular headers?

So you won't see any changes performance wise?

I'd guess that if all tube and collector sizes and lengths are equal...the biggest difference you'd notice would be the noise level in the cab.

Down force? May plant those "mudders" deeper in the ground!

I've tried uprights and down turned headers on my ranger. Didn't really see any difference from 1 to the other performance wise, but the uprights make checking lash when the motor is warm VERY difficult. With a 460 in a ranger, it puts the dirver side header tube right in my face giving me a large blind spot that I have to bob my head back and forth to see around. Also, with the holes in the top of the hood, it makes it easy to get mud all of the motor either during the run or washing afterwards. The big advantage is if you have problems and need to get pulled out of the pit, it keeps collectors from becoming scoops and pulling mud up into the motor.
