Still looking for a used '85 trap cat - PeachParts Mercedes-Benz Forum

Jeremy5848 · #1 06-10-2007, 01:03 PM

I'm still looking for an extra trap catalyst or trap oxidizer for the 1985 300D (W123) with the California version of the 617.952 engine. With a part in hand, I can visit the local muffler shops for bids on fabrication of a 'test pipe.' The purpose is to temporarily replace the trap cat for testing purposes. The pipe will also facilitate removal of the EGR valve as part of the test. (The pipe will not have the extra EGR outlet.)

I thought I had a line on one via my WTB notice in the 'Parts' section here but it faded out. Anyone have a spare trap or a parts car with one? I would prefer to borrow or rent but would buy if necessary. The trap needs to be dimensionally correct but I don't care if the innards are trashed. Anyone?

I have some federal manifolds if you want to convert...

Thanks for the offer. I have considered that but it takes a whole bunch of parts. I'd rather keep the car as stock as possible even if it does mean buying a $45 air filter every year or so.

That's my philosophy regarding the 85 Ca. straight pipe vs. converting to fed. I really don't think there is much more benefit to convert it vs. a straight pipe. Have you already taken your trap off or do you rely on the car as a daily? Perhaps you can measue it, I remember a while back someone posted a prototype of a bypass pipe, maybe if you take a picture of that with some measurements you can get a bid... Just a thought.

Yeah, my trap is still on and the car is my daily driver. As to the bypass pipe prototype that was posted here, I may be able to borrow it. I also have a line on a spare trap. Negotiations, as they say, are in progress.

There are not many parts needed. Manifolds, down pipe and both oil tubes. You can still use the stock air filter setup.

I mean...sometimes unfortunate things happen between long drill bits and Cats. Zero parts required, improved performance and mpg.

I sold one about 2 months ago that had about 60K miles on it.

There was one on craigslist a few weeks back in portland.

I don't know if you'll be able to buy one second hand easily, as the yards see it as a "cat converter"

In all my yard hopping I have only seen ONE car equipped as such.

What more do you need for federal emission parts? The manifolds, air intake housing, and downpipe?

Still looking for a trap cat or trap ox to borrow, rent, or buy.

I've got extra exhaust, intake manifolds and turbo, but no trap, from an 85 Kali.

I have one, but Im still looking for a cal turbo. I have the manifolds too. Soon as I get the turbo, I'll mount them on a piece of board to make a form for the bypass pipe, which means I need the flanges from the trap. After collecting all the pieces, I think its wiser to convert to federal instead of going this route. Ive seen manifolds w/no egr connection, probably from late 70s . I want those.
