look midway down the products page, for exactly what your looking for in a intake manifold.
1G and 2G "FATBOY" Intake Manifold. We designed and built this manifold to allow for a 75mm T/B, with this design the coil pack remains in the stock position. Using the stock runners with a larger plenum gives you better low and mid-range torque than a full race manifold. This manifold design has supported 780 hp, at the same time giving great drive thru the whole power curve. It can come with or without EGR and also for stock T/B set-ups.
PRICE = $498.00 (plus core). Colour = Gunmetal. (custom colours extra $16.00).
Edit! OOPS!. was reading the Todays post listing, and didnt pay attention to the forum the thread was in! Sorry! and i wasnt trying to push product, i simply copy'd the info over.
