I recommend not putting holes in that flex pipe. Mine went last year on its own and it was LOUD. Your also correct in that the amount of dirt and soot in the engine bay is just not worth it.

Mine also did not have a pipe within the flex.

Wow, some of you are making it sound like my car is loud and obnoxious, when all I did was make it so that when I'm accelerating I can hear a slight whistle, just enough to let me know that the turbo is functioning--and I think it is a pleasant sound. It's not even audible when the radio is on.

Even when I had the exhaust removed completely it wasn't nearly as loud as those Cummins trucks or street racer cars. Some people on these forums are much too judgmental. Half the time I feel sorry that I ever post anything.

Have a ball and do whatever you like. Personally, I find any extra noise annoying, especially on long trips; I spent about 50k miles driving last year, quiet is good after the first few hours.

I've chopped the rear muffler can off of both of my W123's I've owned, and I plan to do it to every car I buy.

The PO of my '84 installed a new drop in style K&N air filter right before she wrecked it... I'm running around with that untill I buy a new filter. Holy turbo whistle bat man.

Great videos, Mike! I never really got to see your 240D 3.0. I didn't know you got a 300D to replace it with.

By the way, I picked up a first aid kit from a Euro 280E if either you or Sebastian want it. There are about 5 W123s here; I'm not sure if you need anything at the moment.

Removing that sleeve for more noise, well seems foolish since it is likely there for better airflow = better power.

If you want turbo noise, go to a cone air filter. There is PLENTY of turbo noise on the intake side of the turbo, I can hear mine when driving 75mph with stock exhaust, stock air filter system, just a pipe replacing the AFM in the intake plumbing. We put a pair of BMW/Yanmar turbodiesels in a mahogany boat (Hacker-Craft reproduction) we were building, when we did the sea-trials the Yanmar guy showed up with earplugs, ... the sound from those big turbos' intakes at full-chat was DEAFENING! (3L inline 6 running 250hp).

I agree with both camps really. I love the sound of the turbo, but in my car it seems to be its loudest around 8-10psi, which is right where it runs at 80mph. It gets annoying. On the other hand, I've always loved opening the window on our coach next to a concrete barrier to hear the turbo spool, ... 45feet behind me.

Did you happen to get the rear bumper? I snagged the front but didn't have time to get the rear and it was gone the next day. The rest of the 123s are pretty picked over but the 280 still has some nice interior; Door panels especially, blue visors with clips etc.

Dont you dare take that interior. I have to go back and pull the seats for ducatipaso's euro cloth 280TE...

The bumpers were gone when I saw it. I snagged the switch, check valve, and lines for the euro lamp leveling. My buddies took the new us tails, and black interior trim. I also grabbed the vaccum trunk and fuel cap pods... Oh and the washer bottle.... Oh and a buddy snagged the debadged euro boot lid.

if you are determined to hear more of the engine, take out some of the floor mats and whats inside the hood.

it gets old quick :/

I made a newer cold intake than what my photos show.Filter is at front in the cold air.Some kits they sell are really hot air intakes.
That and straight exhaust plus boost at 16psi,she really sounds good.

If I listen closely with the radio off I hear what sounds like a muted siren off in the distance as my turbo spools up. It works quite well and seamlessly.
Also- it looks to me like that inner sleeve is there for heat-related reasons. My car still has it.

I wish I could hear the turbo spooling in my 240D, but it sounds like it's not there at all

The CDI's are so quiet, you can barely hear the engine, but the turbo sound seems to be quite noticeable, particularly on the Sprinters. I've never been able to hear the turbo whine on any of the IDI Mercedes turbodiesels except when the exhaust or intake have been modified (i.e. K&N filter and/or straight pipe exhaust). I've always wondered if that was an intentional design feature as the whine was an "undesirable" noise for most people.

I haven't noticed any power decrease from the pipe being removed. I might go with a custom air intake, but will do my research to make sure I get a good setup.

The only parts I removed from the 280E was the first aid kit, manual antenna, and tool kit. I'm glad to see others are making good use of the parts. I've seen too many Euro W123s with nice cloth interiors get crushed without anyone buying the parts. At least I got the 5 speed from one before it went away (it's sold).

I don't want to hear more of the engine, just the turbo. I'm not even wanting it to be screaming in my ears, just lightly audible. I have a turbo and want to hear it like the Cummins guys.
