No problem hitting the floor, the problem i the angle of the front of the down pipe (y-pipe). Sorry my terminology is old. Down pipes (originally) are the pipes on the exit of the turbo, the y-pipe has the flex joint in it when held up in the air looks like a Y.

Now newer cars have dump pipes (yes 1997 is newer in my experience) and a connecting Y-pipe/down pipe due to the need to remove and take things apart in tight quarters. In the past the down pipe and dump pipe were all one pipe.

I do appreciate all the help. I have an R33/R34 y-pipe/down pipe. My dump pipes are specifically R33.

The front of the y-pipe/down pipe is angled off by about 10 degrees and there is a 30mm gap on the mating surfaces.
