Undertray and Crossover Exhaust Delete

[KaiPL]

When I got rid of my crossover exhaust, I noticed that deleting the crossover left a big trapezoidal hole in my undertray. I decided to close it up with a piece of aluminum riveted over the hole.

Anyone else try this? I'm hoping it will help my aerodynamics a bit compared with the hole.

Did that hole (intake) also help cool the diff as well as the crossover??

Now we have two good questions above. Never really thought about those things, but having the X-over near the diff, couldn't have helped with the heat situation.

There is a separate duct that cools the diff.
