if i fit a decat dp will my insurance company still insure the car or are decats illegal,
any info welcome, cheers

 

Best to inform them to cover yourself but i guess a fair few dont so its up to you call them up and see what they say ?

 

Can of worms
If its decated then its not fit for the road and will not pass an MOT.

 

Hate to rain on your parade, but if it still has a center cat it will be fine, I also passed the mot with the decat dp the tester just took it out for a little run to warm it up . (my99 classic)

 

Not necessarily at all. Gonzo is more likely to be correct in practice than you are.

a) Your trick only works if the centre cat is in good to brilliant nick.
b) If you get stop-checked by VOSA out on the road, they are unlikely to take your car for a buzz before testing it.

 

not illegal to have a de-catted exhaust aslong as you can prove it passed its emissions test at MOT.

 

does any body know wat size lambda plug usually found on the wrx 95 imports i tried changin ma downpipe and there was a smaller thinner probe than the the threaded kind that was on the new downpipe anybody got any ideas oots there:O:O

 

u could probably get a reducer to accept ur existing lambada probe ..

 

aye bloody nightmare r they usually all spark plug sized threaded probes ??? my downpipe suplied and previous scooby had bigger probes just no sure why cat would have smaller threaded on standard...doin ma nut right in just want lum on it

 

surely the smaller probe you are talking about is the sensor that alerts you if the CAT has got too hot... this is not needed if you de-cat the downpipe though and if connected back up will probably cause the CAT on fire light to come on.

When I decatted mine I left the CAT on fire sensor off and everythings fine.

The lambda sensor on the early WRX's is in the headers not in the downpipe... As I said above the smaller probe in your catted down pipe is just the CAT on fire sensor which is not needed.

so wy on the new downpipe it got the two threaded holes with inserts for them wat they for mate ??i am stumped noo

 

this sensor ur referrin to was it screwed into the pipe just below the cat on the downpipe on the drivers side??

 

Yea I think so, its a while since I had a catted down pipe around... On the new downpipe I guess you might have holes for the lambda sensor as on the later models the lambda sensor was in the downpipe... which is actually a better position for a Lambda. Not sure why you got more than one threaded hole though?

when I changed mine, my new downpipe had a Lambda hole in it too so bought a Lamda bung from Demon Tweeks. I have recently had my engine out and headers off and have decided to move my Lambda from the headers to the downpipe.

my downpipe has the bungs in it so will my standard downpipe fr4om turbo have a lambda probe in it or should i just rubber the probe ..i just cant work out why the downpipe sold has thes in it if u dont screw them into anything...my cars a 95 classic version 1 so is this thing i am wonderin about the flame sensor ur on abouts ...cheers for ur help mate by the way

 

On my 93 WRX version 1, I can say that there is no sensors connected to it and any holes are bunged up. The "cat on fire" sensor on the catted down pipe is not used in the decat pipe... I would assume you wouldnt need anything put into your new downpipe as long as yours (like mine) has the Lambda in the headers, which can be found on the drivers side header. Fairly positive on this!

Sorry to the OP for the hi-jack!!

sweet mate perfect sounds like i will go ahead pretty sure ma headers r lambda`d cheers for help much appreciated .and p.s new to this network so was no sure how to get new thread up sSORRY :O:O:O

 

If you get stop-checked by VOSA out on the road, they are unlikely to take your car for a buzz before testing it.

Have you or anyone you actually know, been subject to one of these checks?
There are some folks on here who know of a person who knows someone who has a friend who heard of someone who was stopped etc.........I've seen the VOSA roadchecks, stopping vans / trucks etc.

 

no prob for the hack lads, all info welcome and useful.

also s70rjw , not to worried about vosa at the mo just wondered if my insurance company would still insure me if i informed them i had de-catted, but no not heard of any one whos been pulled and checked yet.

thanxs for all replys boys and girls
