im buying long tube headers and i have the 700r4, the problem is once installed the exhaust would have to go under the transmission crossmember. they dont have any after market crossmembers to fix this problem so i was wonder if its possible to cut the crossmember and weld some thick metal strap in a u shape so the pipes go straight back. would it still have good enough strength for all the torque?

 

your best bet would probaly be to use a peice of pipe cut in half and weld that to the crossmember

 

There have been posts showing pictures of fabricated tranny crossmembers including ones that loop over exhaust pipes. The floor of a third gen is terrible for a simple crossmember design. It's not a simple "tube from side to side" type of design.

The crossmember is holding up a lot of weight. Just don't make a flimsy design.

 

Do you know where those posts are exactly that would help alot, or do you have any suggestions on to what could be a better design because i have only seen the ones where they do it in the U shape with 3/4 inch pieces of metal. have you seen any other designs other than that one??

Will make a nicer one now that I'm swapping in a 4L80E.

 

Had to edit linked to the wrong crossmemeber

 

so then is there a crossmember that is already made for what i want to do? cuz i have asked different techs from different places n they all say that they dont kno of any places that i could just buy one.

 

NO there are not custom cross members like that available. You're on your own on this one. Look over on the exhaust board and you'll find more pics.
