Rear Diffuser

My next mod was to start the rear diffuser. I will be having a full undertray of coroplast but I need to transition the undertray to the rear diffuser so I had to add a support bar. The bar was aligned so the undertray will curve up and hit the diffuser. Should provide a bit of downforce too .



The muffler is going away but that will be another step.

So the steps are:

1. support bar to screw the diffuser and undertray to.
2. Passenger side diffuser in plastic
3. Remove two mufflers (one is a resonator I believe). Make a new 2" cat back exhaust and install.
4. Driver side diffuser out of sheet metal, with exhaust terminating at surface.
5. Make undertray for the rear bumper at both sides of the diffuse to get rid of the parachute, I have now.
