2020 G63 Muffler Delete,Sounds Wicked!

Hey Guys,

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.

I just showed my wife and asked her is she wanted ours to sound like that - she said no, but I like it!

Is that display available on the 2019 G63s where you get the gauges lit up on the right screen? Haven't played with the custom options all that much.

If cannot find vehicle category then you can simply activate voice control and just say "Engine Data". It will show up on the display.

Love it! I am also thinking about deleting my muffler. Would you mind posting photos of how yours was done? Like under the car? Is it still a Y set up? (1 pipe turns into 2 side pipes)

thanks in advance

Any drone?? When mufflers are removed, it is a common complaint.

Youve got me wondering what a G550 would sound like without the muffler🤔

Easy to find out - just loosen it at the connector forward of the muffler, on both sides, separate the piping and start her up! Should take less than 5 minutes.

Actually, its not that easy to understand drone level because when you run the car without any pipes the sound coming from the cats are quite distorted and unbalanced.
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.

Good point, that part did not dawn on me; however, one can still get an idea of the sound at idle that way, especially when sitting inside with the windows up.
