2020 G63 Muffler Delete,Sounds Wicked!
Really easy job, 15x times less expensive but better than all other aftermarket systems, in my opinion.
I am stil using valves, cats are not removed just straight pipes from the cats to the tips, to use the valve button, we welded another small diameter piping next to the large straight pipes.
IDLE
When closed, it sounds %10 more than stock
When open, it sounds %30 more than stock
CRUISE
Closed, same as stock.
Open, maybe %20 more.
WOT
Now, this is the part that it just screams, i mean now i feel like this car is a completely different animal. I strongly recommend this mod to everyone.
Here is a video, sorry for the ****ty quality, youtube related issue.

thanks in advance
Without any pipes, car will have more drone and unnatural sound compared to a pipe trough cats to tips.
With straight pipes from the cats, you will not have drone, i am %100 sure.
