Hi!

I just watched a video of a guy showcasing his Mercedes C32 AMG and around 9:16 minutes in, he talks about his the previous owner installed a button in the center console that can be used to open up the exhaust sound for a more sporty kind of vibe.
Many modern sports cars have that technology and I like the thought of it. Does anyone know how this is done and how difficult this would be?

I found this from Hot Rod Magazine:
Exhaust Cut outs

 

When I used to race, in the 60s, I had a switch under the dash to open the exhaust cutouts, It was easier than the bolt on plugs.

 

In the 60's 'hot rodders' installed cutouts with a cap that unbolted. This was before other choices became available. Took a few minutes but the end results we the same. Once, a police car rolled up next to me after just uncapping, had to delay my acceleration until he was a car length away just to avoid a ticket.

 

Not difficult at all. When I had a shop do mine years ago they took the second set of cats out and put an electronic cut out in. My switch is cut into the plastic piece where the headlight switch is. Sounds a bit like a boat chugging along at idle but under load I enjoy it. Definitely loud as hell though

 

Sounds like a Jap ricer grinder with fart pipes.

 

Needswings has the cut outs and any exhaust can install them into your exhaust .
this one sounds as it was put in line with the stock exhaust, Maybe mounted just before the resonator,,
but if you look just under the muffler there is a open pipe and he did say muffler delete
a cut out for racing is mounted so you have open exhaust
(loud but more power if modded for open exhaust.)
I did have cut outs on my 10.55 second 1/4 mile crossfire but the mods i had needed more backpressure
so i install 3" exhaust with headers,no cats, no resonator, but ran it through the stock muffler.
( the stock muffler has 2ea, 2.1/4" inlet and 2 ea and 2.5" outlet ) jim

I believe this setup may have some extra pipes bypassing the muffler or resonator (with the cutout in the bypass). Without seeing the piping, and the camera just focused on the exhaust pipes, the exhaust seems to sound like it is still going partially through either the resonator or partially through the muffler. Too bad the video posted doesn't show the piping. Can't tell if the cutout is dumped under the car (although I believe the sound would be MUCH louder).

So much good info and food for thought here. Also liked the article..I will further explore. I think it might be time to start exhaust tuning a little for extra power as I have exhausted a lot of other tuning options. But I don't want it to sound annoyingly loud in the roadster which I always liked the new sports cars that have s switch to make the exhaust sound more of less sporty depending on what you are doing or where you are driving.

 

I have the Valvetronic system on my truck. Should I ever replace the Magnaflow on the crossfire I will probably do cutouts.
