As the title says, "T Rex" failed its technical inspection because of the secondary cats and resonator bypass pipe

Every two years vehicles on the road here have to undergo an official technical inspection. After a thorough wash of the chassis, a steam clean of the engine bay and a service, the vehicle is presented to the test centre.

Everything which is safety related is obviously inspected and if anything is not normal, or you have non homologated aftermarket goodies, the result of the test is FAIL. You then have to get the vehicle repaired and retested to remain "roadworthy".

The KW suspension was inspected and deemed OK, same as the SS Goodrich brake pipes. I have official homologation documents for these items. My drilled OE rotors and EBC Yellows on the front passed unnoticed However, when one of the technicians was looking closely under the vehicle, he said to his colleague "hmmm, looks like the exhaust resonator has disappeared...". I thought that they would not see the modified exhaust, but they did.

Next step? I have to reinstall the standard exhaust, get it tested again (just for the exhaust thankfully) and when I have the official stamp on the vehicle's documentation and everything is fine, I can remove the standard exhaust and get the "V8 sound machine" back on. Oh I nearly forgot, the 18" monos are not homologated for the w202, so I switched back to my 17" before the test, so those will get exchanged back to 18"'s also.

Wow, pretty heavy handed on the government's behalf. Glad you've got a way out though.

Thought the ****'s lost the war?

sorry to hear about your mishap dude.
how much did the test cost?

did you drive your car properly to get the cats warm?
driving your car 30min - 1hr to get it fully warmed b4 the test is a must to get good fume ratings!
2 front cats should do fine on your car as the rears are only passive.

every 2 years you have to switch back n forth when doing the test is a PITA as it cost money if you don't switch pipes your self!

I do the change of exhaust myself. Emissions test no problem with or without secondary cats. It is a tough life here if you start doing mods on your vehicle or you have to be smarter than them. For example, a 55 swap would probably pass no problem as the engines are identical

can you help me out?
i need to know how many flanges there are total on our stock auspuff?

also how many flanges are needed to buy extra if removing centre silencer and rear cats?

do you know any good sites selling SS flanges for our cars?
how many 60mm flanges are needed and how many 70mm needed?

I'll check later as my exhaust is in parts in my workshop, but I may not be able to look into this for around a week as I'll be away.... Is that OK?

Its usually happen with Emission system, if there is much dio. carbon in the Exhaust muffler, when you not exceed 40mph for long time,,

or some kind of dirt clogged the EGR more than 60%, did you look on it.....??

ZAYED,,

There is no problem with emissions. I just need to put my OE exhaust to pass the test and I'll remove it after getting the green light ;-)

as long as you don't forget about it, it's cool I can wait.

That is absolutely outrageous and downright tyrannical. I find myself breathless at the situations some other nations deal with by simply owning a car. Don't even get me started on the UK style insurance system. That is downright tyranny designed to keep people in public transport controlled by the state.

please educate yourself

wow, I didn't think my thread would rise some negative feelings

I think "Sulaco" input is reasonable, some countries got a free minds & moods to let everything important behind, and focus in the Auto things....,,

why they failed the gasolines car emissions test..?, is that because of much carbon % comes out from Exhaust, if so, then what

the damn hell that Diesels cars do in the street, when i stopped behind Buses or trucks or any Diesels tails,

my face become blue & my chest filter clogged....!!,

where is the fair if we need to comparing between small gasolines & damn bubble huge Diesels....?!!?,,

governments doesn’t focus about Diesel tails, they only happy to concentrate about a lovely cars, like ours.....!!!!

ZAYED,,

Not really sure what your going on about? I was just making a joke about a overbearing government system that limits the use of aftermarket parts that are not approved buy a government run committee. As well as the need for homologation papers for parts on ones personal vehicle. Another poster referred to them as the Swiss mafia. Hence the correlation between the Swiss transportation department and the thankfully short lived German **** government.

But if you still think I'm in the wrong send me a private message as our conversation has nothing to do with the OP's thread.

I hear you man, just don't think it's funny to make jokes about ****'s...........and I am German, well part German

Not to hijack, but I once got a ticket in my 240d for it being "too loud" and was a "danger to the public." The cop was being a total dick and the judge threw it out.

While he was lecturing me about how deadly and dangerous my 30 year old, 70hp diesel with a hole in the muffler was a danger to everyone on the road, several rednecks in giant trucks with LOUD exhaust drove by, so loud that he had to pause and wait for them to pass. Funny, he didn't go chase them down and write them tickets when they were easily double the volume of my w123 (which I was ON MY WAY to get fixed!)

I don't respond to overbearing authority very well.

Ahh, that’s the point,,.....>>MOOD>>MOOD>>MOOD<<.....

soo silly, left everything around, and ask himself, ohh waaaaw what an oldy toy, i have "4" ours till my job finish,

what about some amusing with it.....

ZAYED,,

OK people, let's cool things now...!
