any of you out thier know if i were to purchase the hedman LT's i could have enough clearance on the drivers side header to run a somewhat stock routed y pipe back over to the passenger side to meet up with the passenger side and back into a single stock routed exhaust?

No, nothing like stock-routed anyway.

do you know how far back the drivers side tube comes? im trying to find a way i can make the exhaust pipe off the drivers header make a route back to the passenger side.
if its not gonna be feasable ill go the shorty route

Pretty much even with the back of the block. There have been a few pictures of dual exhaust setups with Hedman LTs posted you could look at to get an idea. I don't really think it's possible to cross over anywhere ahead of the transmission.

if its even with the block, any chance it would be feasable to have the exhaust make a 90 degree turn right off the header, or even 110 degrees to bring it back some to clear the inspection cover?

A sharp bend like that would probably negate any benefit from LTs, you wouldn't have much in the way of ground clearance, and it would be pretty hard to change your oil filter.

i run hedman longtubes, into their extensions w/ the little bend in them to clear the crossmember, then i have pipes running around the tranny pan, into a flowmaster y collector, then back into a 3'' dynomax catback w/ an 80 series flowmaster.

I used the dynomax pipes instead of straight up buying the flow catback to save some money, plus I'm going for the stock/sleeper look, and the dynomax tailpipes are exact stock identicals...save for the mandrel bends and are a 1/4in bigger.

looks and sounds awesome
