when i calculated out(rough from formulas) the primary length i came up with 27.2inches with a 1 3/4 primary. looking to use a 2.5 inch collector and flowmaster scavenger y-pipe into a single 3inch.
there is a ton of room in there, especially since we are "fixing" teh air condtioning tomorrow.
now i jsut have to talk him out of the power steering and there will be all the room you could ever hope for to use wider elbows and longer straight sections in the construction of the tubes.
later
