Primary Tubes Designed for Low End Torque

[Indycars]

I found the header design I want for my TBucket !!!
Should give me lots of low end torque :lol:

yeah! provided you never reve the engine much over 1600rpm :mrgreen: :lol:
obviously someones got a rather odd sense of humor, too much money, spare time and a welder....
bet that results in tons of giggles changing plugs when the headers are hot??
its got to be really neat on rainy days seeing where your going with all the steam coming off them also

here they sell much better designs if you want to be a bit exotic

USE THE CALCULATORS to match port size to intended rpm levels... but keep in mind valve lift and port flow limitations

They might even provide some heat for the passengers, which would be nice in the winter.
Speaking of steam, they do have some benefits with the Steam Facial for the ladies!
