Sheet metal rear diffuser and transmission under panel for your MR2! Based on the prototype I described in my blog, with some improvements and additions. Laser cut and CNC bent from a combination of .100in and .050in aluminum sheet.
This diffuser will NOT fit any existing MR2 exhaust other than my center exit Borla for 2GR swaps. For non-2GR applications, a custom center exit exhaust will be required. I can sell you just the muffler section from my exhaust, and a custom mid-pipe would need to be made to complete the system.
Installation will require drilling two holes in the rear cross member and installing rivnuts in those holes. A half dozen holes in the rear bumper beam will also be required. The diffuser will ship disassembled, and unfinished. Assembly and installation will require a pop-rivet tool, and a rivnut puller.
The prototype on my car. The production version is slightly wider, extends slightly further forward, and has an extra vertical divider in the two side tunnels.
