Old setup had the exhaust going through it, just kind of figuring it out as I go. The diffuser took some damage from racing so I had to rebuild my rear mounts. Decided at the same time to change it up some, lower it and bring the exhaust out above the diffuser.

The entire diffuser is 6' long and goes a good bit past the rear diff. I also run a diff cooler since I am not getting any airflow to the diff now

New setup, you can see how much shorter the strakes are so I can reduce the angle of the diffuser.

This was before finishing things up but this is the front half under the car before I added 1" strakes to this piece (which have no been mostly ground down flat lol)
