This is where im at now both sides will get boxed in twice inside original subframe.The rear will get plated and welded to floor.The driver side will be continuously welded to floor pan.The passenger side gap will get a half moon of sheet metal to match floor contour on both sides of tube.I will copy the mustang mount.This not for everyone but I cannot stand the sound of a crossflow muffler.I also dont want dual exhaust run under the factory transmission mount with little ground clearance.

This will be long tube headers to H pipe hung of off of factory transmission exhaust hanger.It will be 2.5 inch dual exhaust flowmasters under rear seats.I will raise the floor pan under the rear seat for more clearance.It can be done and still have the seat bottoms look normal.From there up and over axle the drivers pipe will go to passenger side then over axle.The drivers side exhaust will exit passenger side.The passenger side will be routed to drivers side for exit.

Success crossmember holding the weight ! Now Ill trim down the mounts and shape them like the crossmember and cap them.The headers can come out now and I will weld the ball and socket exhaust ends on.The passenger side will get turned away from transmission.Still got some welding to finish in this area then to the rear seat pans.

New headers came and did a test fit before finalizing this section. The old headers on passenger side it faced right into the transmission pan and angle was terrible. The new headers are perfect and the UMI kmember was worth it, plenty of room.The Hpipe will go right at end of transmission and Ill continue rearward

Floor patches done and bedlined

Test fit and seeing how it looks,im going to take it back apart push the Hipe farther back and move pipes up into transmission tunnel more

The rear is supper simple waiting on a 25° bend to come in with couple extra 90° bends
