I’m confused...both my ‘94 420 and ‘92 400 parts car have the same OEM 2-piece setup, 1244912300 (center) and 1244911000 (rear) joined with a standard MBZ clamp, as shown on my EPC.
Were perhaps the cars delivered new with 1-piece setup from the cat back?
If the 400E pieces are clamped together, they are replacement parts, not originals. These will be a slip-fit with normal external clamp.I’m confused...both my ‘94 420 and ‘92 400 parts car have the same OEM 2-piece setup, 1244912300 (center) and 1244911000 (rear) joined with a standard MBZ clamp, as shown on my EPC.
Yes. From the factory it was a 1-piece assembled welded together.Were perhaps the cars delivered new with 1-piece setup from the cat back?
Any 400E install is going to require welding. None of the aftermarket Y-pipes are designed for a slip-fit; at least I've never seen one.So, then, factory part, on 400E does not to be welded?
Dave, as always thanks! Looking at TimeValve, I only see this:
Is exhaust on 400E identical to a 1986-1988 300E? Also, do you think there is any detrimental effect of a leaking exhaust in my case? It's not particularly loud. Somewhat resembles a late 60s American V8 idling

A competent exhaust shop (and I would look carefully to find a good one) can work miracles, and it would be NO PROBLEM to have them weld on both extensions and flanges to adapt the Y-pipe to whatever situation you have.Today I figured out that 124 491 23 00 is a resonator + 2 in-flow pipes - as one piece. My usual go-to shop that said I need 124 491 23 00 to fix the leak is busy, so I took it to another shop, where guy actually showed me where the leak is (see red arrow; it's on the top of the pipe)

What I also realized is that Gerry's Y-pipe (top) is not long enough to fully replace 2 pipes that flow into the resonator, unlike Time Valve's (bottom)

Now, you can see waht my original piping looks like, and the guy from the 2nd shop says, that although Gerry's Y-pipe is just long enough to cover the hole, he won't do it because both in-flow pipes need to be replaced. He sent me off to find replacements, but, as I've just figured out, they are part of the 124 491 23 00.
Question to @gerryvz or @gsxr , how much time do you think it should take a shop to fabricate pipe extensions so that final product is equal to proper 124 491 23 00/Time Valve unit? Alternatively, would you just find another shop that will weld in Y-pipe as is because my 2 in-flowing pipes look otherwise OK?
Thanks
Terry, the 400E resonator is different than the 500E. It doesn't have bolted flanges at each end... requires cutting to install, if the original is still present from the factory. See pics it post 12 and 24. Can't see enough of the pipe between resonator and muffler in post 24 to determine if that unit is factory original (welded) or a slip-fit factory replacement.
New 400E resonator is $630 list, ~$500 discount... should be available in Germany. MB generally doesn't stock this stuff stateside which may be why only 1 was on this side of the pond.

AH! Got it... in that case, $1k is not bad. The two items are $1200 MSRP combined, $900 from Naperville.Dave, I'm getting #4 and #5 on the diagram from the link you posted.
Done! I keep forgetting to check messages...Also, please reply to PM I sent you
Kiev,
I have the Timevalve Y-Pipe on my car. I will post some pics later this AM.
I bought mine before they moved the shop to Florida. I’m sure they still have the jig.
Not sure what the price would be today. Mine costed over $300.00 quite a while ago.
lol
Edit:
Here's my Timevalve set up.
Sorry for the delay I got busy and forgot
Those 2 rear pieces look mint! I'm sure someone with a 400E will snap them up. If not, drop me a line.Nice front pipe/cats taking even longer to extricate; just not the man I used to be.
And it would probably be a challenge for me to ship.
If you’re getting truly OE parts, not Eisenpacher(?) aftermarket, shipped and installed for $1000, you’ve done pretty well I believe...
As your problem sounds solved, for someone else’s future reference:
I FINALLY removed these (almost new) 2 exhaust pieces from my 400 parts car...

Timevalve only makes the Y-pipe. They don't offer a muffler for the 400E or 500E that I'm aware of.Terry, just to clarify, both Y pipe and a muffler are from TimeValve? How much different the sound is vs stock?

Only aftermarket mufflers I've seen are RENNtech (NLA), Remus (NLA), Brabus (pretty sure NLA), Fox and Leistung (still available).
Here is the Y-pipe (not the Timevalve unit)
Glad you finally have this resolved! I remember when I removed the resonator at first, same thing, no notable difference that I could recall (but that all changed with Carlsson rear box)I've finally installed the Y-pipe. Was charged 2.5 hours of labor by local Midas to adapt it to my 400E. Barely, if any, change in noise, but there's a slight turbo hiss now.
Is this, supposedly NLA, 1 year old center muffler for 400E that was cut out for Y-pipe worth anything? Cost me $600 a year ago![]()
Carlsson rear box
Find a 2.65 rear differential from 90-92 500SL and then you’ll want that fancy rear muffler.That'll have to wait. Rear muffler, just like the center muffler, is only 1 years old. I can't throw it away too, this quickly. I was hoping for a very mild improvement in sound using Y-pipe instead of center muffler, but it turned out a lot more milder than I expected. Did not pursue rear muffler mod because I thought it'll change the sound MORE than I would prefer. My car is a staid 400E, not a arabic stallion 500E, so aggressive exhaust sound, I think, would not match its character

The 2.65 will totally transform your car
Yes sir, mine has no ASR. Just make sure there is just one sensor on the differential and you are all set. They sell for only around a $100 in Nor Cal at the dismantlers.I know. My car does not have ASR. Were there 90-92 SL500s without it?
