Took us about 2 hours for the headers and 3 for the exaust system the next day. Tubular headers are much more free flowing then stock intake manifolds.

Comon, 12hp from headers on a stock truck at the wheels?

That is close to 20hp at the flywheel.

No offense rlith, but that sounds a little overzealous in my mind.

But on the other hand, if it is true, I might be in the market again.
