I had a small crack in that flex pipe on my 300sdl. Performance was sub par below 3500 rpm and it would smoke badly between 2000 and 3500 rpm. Soot was also a problem and the only reason I found the crack

Hey! You can just drill a hole in the air intake box and jamb a whistle into the hole.

This way, even a normally aspirated diesel can sound like a big-boy with a turbo.... fool them all. At least until it comes time to move the car quickly.

... Or just make zoom-zoom noises while driving.

This thread is too funny - a bunch of folks comparing turbo whistle to rice burners, harleys with no mufflers, etc. Its turbo whine..

It's just silly.

Turbo noise is annoying, especially on trucks. My ideal vehicle would be silent.

I really wish that people would keep their negative comments to themselves, though. There are lots of things I don't care for, yet I don't go around saying "that's stupid" to everything I don't like. I guess some of you shouldn't be driving diesels if you don't appreciate the sounds that the engines make.

Most of these Benz forums are made up of Aryan worshippers of cars.
They think its unholy to custom a Benz.They don't understand it will rust and decay like all cars one day.
But remember they are alot of customizer and engine builders that can make these cars even better.I'm with you.

It's quite interesting because I tend to be a purist overall but sometimes I like to customize here and there. In fact, most people who know me say I am too much of a purist. But then I find that in the rare instance that I change something from stock (even going to Euro lights) I get slammed all over these forums. It's a bit odd.

I found it quite entertaining to see some folks grasping at the most insignificant excuses as to why they wouldn't like it. The "thats the way it was designed and its for a reason" argument holds water for me, but the members implying they're going to be woken up in the middle of the night by a slight turbo whine is just hilarious! Dem turbodiesels, they got dat WHOOO WHOOOO!

I like the noise too, I remember I had it a bit before I swapped the engine over to my other SD but I found that the intake U-duct wasn't installed right. Now that its on there i can't hear it one bit, installed a boost gauge to make sure its still kicking in right. I'd imagine that intake modification would result in more audible whistle than the exhaust though.

Some modifications are useful; they improve performance, improve reliability, improve appearance, improve comfort, improve usability, etc. Some modifications are just silly; which type is this?

I would guess this falls under the heading of 'aesthetic', done for the pleasure of the owner.

depends on who you ask. How would this be any different than one made to "improve aesthetics"?

I'll bet he even tampered with the brilliant, rock solid MB engineered air cleaner on his W116 300SD...

Now, how could you POSSIBLY improve on THAT?

I don't know, mine work perfectly. They will eventually break if your engine is trying to shake itself to death.

If someone finds noise aesthetically pleasing, they should have a ball.

Ditto! I call these cars "mild customs." I am all about taking a car - any car - and doing things to the appearance or inner workings that are subtle, so that the discriminating person looks at it or sees it and realizes that there is something no-so-obviously, yet tastefully, different about it. If Mercedes had not done this very thing with the W126 SD by extending the rear door and roof line slightly, and making it an SDL, I would have. Its the subtle changes that can really set a car off in looks, sound, or mild performance and make others fall curiously in love with it.
