Sound tube delete
 

I decoded to take off my sound tube today. Is it ok to leave that hole in the firewall open or do i need to find something to plug it?

I'd find a plug. No sense in letting fumes and bugs have an easy way in. The plug that came with the JLT didn't fit worth a damn, had to silicone it to keep it in place.

how quiet does it make with a stock exhaust?

I took my foam out today......idk why you would leave the foam out. To me it was annoying.

Firewall plugs can be found at oreillys or auto zone ask for a ford master cylinder gasket. It should fit in the hole for the sound tube.

Wonder if this would improve my sync communications?

Why do you guys all delete the tube? I for one enjoy hearing the engine and intake, especially with a boss im ans cai. To each their own I guess.

Well, with my setup, you can no longer hear anything from the tube anyway, so why not clean up under the hood a bit?
