what difference does a decat make?

[leon-and-vicky]

ive just booked my car in with charlie for a decat.just wondered what difference people have noticed with a decat fitted.i have a scorpion cat-back system aswell...

gone from a decat to sports cat. I actually think there is more power with the sports cat. Managed to spin the wheels quite nicely at top of second yesterday. Might have just been the ambient temperature though.

Pah!

Mine went in 4th the other day (Toyo T1-S, wet greasy road, bump).

Fred sells de-cats but the jury is out on whether they produce any WORTHWHILE power benifits. Juxtaposed against the real threat of being prosecuted for having one I'd say do'nt bother.

just gone from prospeed decat back to standard system... and noticed a big difference.

When i had it on... i always said there was bugger all in it... but when i took it off, i lost a massive kick after 5k

Decats ftw.

Have tried mine with it on and off a few times, feels like theres a sponge stuck under accelerator pedal with it in, soo much rawer without.

Gaylord?

I didn't like the sound of the decat on the 182? Sounds too raspy?

 

[Peperami]

Depends what exhaust you have it fitted to though.

 

[leon-and-vicky]

i hope mine doesnt sound too loud.ive got a scorpion catback at the mo and it sounds nice and deep on tickover and not too loud on the motorway.

 

[izibizi]

it will get much louder

 

[daviebroon]

you can get silenced/unsilenced...

... i had the silenced decat and even that was very loud!! Sounded really good though

 

[leon-and-vicky]

i know ill have a word with charlie and see what he says bout the silenced one

you might notice its harder to get through an MOT

edit: I always thought post 1994 cars that came with a Cat had to have one to pass an MoT, but I just read that aslong as it still passes emissions it is ok. Which one IS correct, just seen two different sources say different things

 

[leon-and-vicky]

its a removable one that i can change for the mot

It is not part of an MOT test to actually check if a cat is fitted, it was only law for manufacturers to fit cats on cars.

So if you car without cat passes the emissions test then your car is MOT legal. Some care do pass but the clio is not one of them!

Also you will face another issue with insurance, as very few insurance companies will insure a car with a de-cat fitted.

I've not seen an insurance company yet that likes them sooo...

 

[kully]

better exhaust as you have less restrictions

 

[daviebroon]

mine passed the MOT with my silenced prospeed decat on (with second llamda sensor looped out)

 

[leon-and-vicky]

had my de-cat done saturday and im not sure but i think its slower:S
its got a higher pitch sound than before and pops more but i didnt notice it being quicker :S
is it just me or has anyone else had this?

 

[clio_luke]

i dont think mine is any slower but its not any faster, not really much louder either

Had my decat + Milltek done yesterday (coming from a standard setup) and I too think it has noticeable less torque. Also the 5k rpm kick is less pronounced, maybe it's just a feeling :S .

Love the sound though..

I had a prospeed cat back. Then went to a GDI/Piper with Janspeed decat.

Out of all the mods I've done (Maxogen,GrpN ECU, Inlets, Fuel pressure regulator) this was easily the most noticeable. Wants to spin up in first in the dry now, which it never did before. More power all through the rev range.
