I love my open dumps. I actually have 3 open dump wgs right now haha. I have a 38mm on each bank of my single turbo exhaust y-pipe that dump under the car. I was having problems with post turbo exhaust pressure so I added a 46mm on the down pipe that dumps out the passenger fender when under boost.
They make a loud raspy sound when they open. Some don't like it, I do. Just depends on your taste I guess.

I'll see if I can find any of the fender dump tube.

The fender dump with a ring set my friend/fabricator made. There is a thin piece of sheet meta you need to cut to run the pipe but it wasn't nearly as hard as I thought it would be.

Pulling the whole system and going a new route this winter. Going to have a 60mm wg dump out the fender (2.5") should look sweet.
