4x4 or 2WD? Some of the trucks had a double hump transmission crossmember,as some had true dauls from the factory.

On a 2wd you can go under the crossmember. On a 4x4 you have plenty of room on the drivers side above the crossmember on the right side you have to go between the transfer case and the frame.

81 scottsdale exhaust

it is a 4wd and i have enough room for going over the crossmemeber on the driver side and could possibly do it with a couple 45s then just straight pipe it but on the passenger side i have the t case hump and front drive axle that is in the way and i hear that id need to use 90 degree bends to get up over the t case but idk what to do
