Learn to weld, and make a pipe, or find a welder who will do it for you.

A person I know who works in demolition, took off his Trap Oxidizer (in the late 1980's).
He bought an auto paint quality respirator, gloves, a large pry bar and sealed hazmat safety goggles.
A week later he called, and asked me to reinstall his Trap Oxidizer.
It was an empty shell, remounted easy, and increased power.
I was asked to install it because he had burns from the dust reacting to his sweat.

I do NOT in any way suggest, endorse or consider this an acceptable procedure.
The material inside is VERY DANGEROUS to your health = external burns, blindness, lung burns, death.

How Do I Work Safely with Oxidizing Liquids and Solids?

What is a Class C - Oxidizing Materials?
Oxygen is necessary for a fire to occur. Some chemicals can cause other materials to burn by supplying oxygen. Oxidizers do not usually burn themselves but they will either help the fire by providing more oxygen or they may cause materials that normally do not burn to suddenly catch on fire (spontaneous combustion). In some cases, a spark or flame (source of ignition) is not necessary for the material to catch on fire but only the presence of an oxidizer. Oxidizers can also be in the form of gases (oxygen, ozone), liquids (nitric acid, perchloric acid solutions) and solids (potassium permanganate, sodium chlorite). Some oxidizers such as the organic peroxide family are extremely hazardous because they will burn (they are combustible) as well as they have the ability to provide oxygen for the fire. They can have strong reactions which can result in an explosion. The symbol for oxidizing materials is an "o" with flames on top of it inside a circle.

Now aren't you glad you didn't unbolt exhaust stuff and jump to conclusions as was suggested in the begining.

Always do the cheap easy maintenance things first and then work you way to more and more complex of situational problems.

The SD is getting a fuel filter change becuase its power is very sporadic and been on the low as of late. I figure 30k running bio-d, WVO, regular diesel, etc. has probably finally used up that filter.

I gutted the thing, eye protection, mask, and gloves are required. I have the connections to have cats removed when I need but I didn't feel like dropping the cash to have this done.

Do anyone of you successfully use the aftermarket exhaust pipe that is on Ebay? Are they junk? Just curious, and interested in knowing - just in case.

i had a clogged cat on my '80 jetta gasser. took her to the indy who said they couldn't see anything in the cat because of all the stuff in it so they dropped it a few times and all that clogging stuff came out and they put it back on the car. it ran fine and passed emissions. sadly he moved to alaska more than 10 yrs ago.

Never would have in the first place, nor would I mod the exhaust. When I bought my 95 E320, the exhaust was on it's last legs, and it was leaking, rusted full of holes. 17MPG highway TOPS. Replaced everything aft of the catalytic converter. 15-18 city, 25-27 MPG highway. The germans are crafty and the systems installed all work together and are engineered work together for the best outcome, granted the Trap Ox was a failure, but the replacement exhaust improved performance with newer technology not available in 87 when it was new, but readily available in 1997 when it was retrofitted, by the manufacture, and not some garage guineas. sorry. but the OEM works for me.

[QUOTE=markg612]87-300D Turbo (603.96) (185K miles. owned since 10/96)

Over the last year or so, the thrust so to speak has been dwindling on the high end, I could drive 100mph+ sustained or pass with rocket like performance with no trouble, and as time has past over the last 12 months or so, I notice a "missing" like behavior early on during high load passing where acceleration was very brisk, and then I felt a missing like hesitation, though very slight as rpm and load climbed. This has given way to deteriorating performance on the high to midrange now, were 65 mph is a chore.

Mark,

'Had similar experience recently. The problem was the secondary filter - and at only 20K miles since replacement. The pre-filter was clear.
