de cat... how effective?

[ck786]

how effective is doin this.
wat kind of power increase r we lookin at...
wats the pro's and con's of doin this...
and finally is it actually worth doin..

cheers

 

[chauster]

none unless you remap it after you put your decat on, worth doing if you want it louder.

 

[kully]

less restrictive gases , more power , more noise , can cause higher emissions causing problems at M.O.T time .

 

[Greeny.]

Doesnt really gain you much power from my experience, just noise, also moves where your peek power is made.

 

[Fred@BTM]

it DOES allow the engine to go up through the revs easier, definite power increase, but you'll only probably notice noise increase

 

[theduck]

I put one on my 1.6 and was THE best mod I did

 

[Rob R26r]

Worth doing if you intend on doing other mods too.Pain in the arse at MOT time though.

I have a feeling that Decats will fail an MOT.... so you will have to change back to the normal cat exhaust when it comes to MOT time...

Nigels clio 172 with decat passed , lucky bugger :quiet: , my sports cat was border line , just below the limit

 

[theduck]

Decat will definately fail MOT due to emissions....

Unless you have a bent technician

 

[Ali]

^Not defo! But more than likely.

aww never... Yes i think one of my mates cars also passed with a Decat:quiet: but i aint really heared of that many pasing....

 

[kully]

true

 

[mattjk]

^ depends how far away from the exhaust you hold the probe i suppose lol!

 

[Fred@BTM]

or if the probe isn't even anywhere near your car

 

[kully]

or if the probe isn't even anywhere near your car

the better option

 

[Chally]

Yes this could have a positive effect on emmisions... lol

 

[Fred@BTM]

or if the mot tester happens to have a standard 172/182 then even better!

 

[ditz]

or if the mot tester you work with tests your car while sat in the office eating a kebab you have just bought him

 

[Schweppy]

Are decats standard size for each model? So i could buy a decat for a 182 and it would fit standard exhaust and an aftermarket one?

 

[kully]

yep , most are design to work with std and aftermarket one iirc

 

[Schweppy]

Cool, so wheres the best place to get one from? (sorry to hijack) I know Yoz do them but anywhere else?

KTec do 2 different 182 decats?!?!?

 

[theduck]

all the tuners do them

 

[kully]

take your pick tbh , all of the big boys toys companies will do decats

 

[Schweppy]

OK seems that £100 is average price.

Although Ktec do a milltek only decat for £50. Why is it different?

 

[kully]

decat is technically just a pipe linking the manifold to the rear exhaust iirc

 

[Schweppy]

OK thanks

[Jamie]

Yeh their RS one is 100

One of the mods, Tom i think, was gonna look into getting some made!

 

[MarkCup]

Of everything I have done, if I was starting from scratch again, I'd do the decat thing first before anything else.

 

[Mark One]

have you heard about some emissions tests on old cars?

Mates dad has a jensen crysler v8. The emissions test for that come MOT time is to "check for black smoke from the exhasts"

As long as it's not throwing out soot, it's all good.
LOL

 

[Mark One]

what about the laws with regards to decats?

If you get pulled and a copper discovers (even tho they wouldnt) that you have a decat, do you get bummed?

Only if you ask the officer nicely :rasp:

 

[kully]

worry it get pulled by a vosa vehicle

i know summert that invalidate your insurance as they are mot failures due to high emissions , but you can state on certain insurance co. that you have one ?

Nope. Its not illegal to have a de-cat, its illegal to fail an emmissions test.

Failing a MOT on emissions is the same as failing it on a light bulb. You'll just have to get the problem sorted before getting a valid MOT certificate. At that stage, its nothing to do with insurance

You could invalidate your insurance if you put a claim in if you have a decat however

 

[Sean.]

If you all knew the regulations for an MOT then you'd be better informed!

For a car to pass MOT it must have a CAT fitted. Irrelivant if it would pass on emmision or not. If it hasnt got one, its a fail!

This is not the case for cars older than a certain year (cant think what year that is now) but all those cars that passed with decats either got very lucky with a dumb ass tester or was tested by a dodgy MOT firm!

This is FACT 100%.
