[silvermarty172]

Welcome to ClioSport, silvermarty172

 

[Scrooge]

Welcome, and it more than likely won't pass.

I put my cat back on come MOT time.

 

[silvermarty172]

Ok thank you , just thought it was a cheap option as the weld has gone on the cat but can be welded , what do u gain from de-cat ?

 

[Dave Hester]

Nothing but extra noise

 

[silvermarty172]

Oh right thank you , probably best just to get it sorted then

Mines wasnt as boomy when i fitted a decat. With the cat in place it was annoying driving at 70mph. It also made a difference in performance. Not huge but noticable.

On MOT, i've seen some cars still pass with a decat but most fail emissions

 

[silvermarty172]

Oh right well my mate just told me he has a decay pipe of his clio so probably put that on then it gives me abut more time to get a cat , thanks

I'm gonna get one once it's through the MOT and preserve the original for 1 day a year. I dread to think how much a new one would cost!

 

[silvermarty172]

That's the thing mines just been mot'd and passed with it blowing ? so may put it back on just for mot and hope it goes through again, there not to bad tbh I was quoted 218.00 fitted but would rather spend it on something a little more exiting lol

My decat has made a small improvement to my 172.

I really need a to fit your bucket mod, to make some worthwhile BHP gains.

 

[Iceberg_172]

Mines the same,

O have a 172 cat for sale for £30 :-D

 

[silvermarty172]

How much do u want to post it ?

 

[Dan]

my 182 passed with a decat on

 

[silvermarty172]

I've been looking all day and everyone says different lol , only one way to find out I suppose :S

 

[Dan]

its a free re-test so if it doesnt pass it doesnt matter too much lol

 

[silvermarty172]

Lol Yep very true , gotta be done then

Hmmm wonder how much that would cost to post :-S if your intrested PM me your number and i will find out for you.

Removing the cat will fail the test. Really don't understand why anyone would want to mess about with removing the cat and then refitting it for the mot and then take it off again. A lot of extra work for no real gain. Just get a decent exhaust system and that will give you the power gain you're looking for. I've got a Scorpion cat back stainless system and it's great.

 

[djjonnibgood]

It's only a ten minute job, and it you've got it up on the ramps doing the oil it saves stood watching the oil drain out

On a 182 it is. On a 172 its a right royal pain to change

 

[Boertjie]

guys,what is MOT?You lost me now...

 

[.Tyler]

Just don't do it unless you want the extra noise.

I have a decat on my RS192 and I love the sound but in hindsight, it's not worth the hassle. I did notice a slight improvement in throttle response and it seemed a little more free-revving. But this could have been a placebo or it could have been the exhaust itself making the difference.

What about de-cating a diesel ? Will that fail its mot also ? And i read somewhere that it makes the turbos spool up faster as the exhaust gasses escape quicker ?

Just no. Remap.

 

[24JSeymour]

Its a 1.5 dci 86hp, theres a company near me called big fish tuning that say they will be able to get it to around 110hp, think its worth the £250 ?

 

[.Tyler]

Personally I'd say it'd be well worth it but I don't know anything about these engines or what the implications could be.

Do a search and see what you can find, there should be plenty of dci owners who have had experience with remaps good or bad! Or start a thread about it and hope someone in the know is kind enough to advise you...

I see no reason to bother now on a road, especially with the new regulations come MOT time.
