decatt..

[Seymour]

My mates got an astra VXR and hes got a decat on it, sounds amazing always popping... anyone got a decat on the polo? and im not sure but dont VWs have sensors in the cat?

[KennyPOLO_Gti]

I have got one, simply remove the probe, put it in some sort of pocket and tuck it somewhere out the road. There is a plastic flap that you can squeeze it into. job done, no ecu faults etc!

i had a decat on the gti and did sound mental dont pop all the time though, yup vw has lamda probe sensors in the original cat section you can have the same fittings welded into your decat part so your sensors are still there but you will get engine emmisions light up

when i had mine done i had stage 2 remap and got j from more bhp to map the lamda probes out so no warning lights

few people now got decats now so someone else will have some info also

i have a decat and have done for a year, just put your second sensor in a metal sleeve and tie it out of the way, doesnt pop alot as the turbo is small but does now and again when changing gear! Defo sounds better without the cat!

[Seymour]

Can you get one with standard exhaust? if soo where ?

[whitegtipolo]

powerflow or another place like that can make you one , made my 2.5incher!

I have a amd remap, wud decat effect the map? Would it need remapping?

[KennyPOLO_Gti]

No further mapping would be required. If i were you i would get the downpipe done at the same time and just sit the sensor out the road same as me and chris and you'll be problem free Mines pops all the time and flames when booting it!

[Gillen]

What's the advantages of decatting? Any disadvantages?

[KennyPOLO_Gti]

More free flowing, which is what you want on a turbo'd car.

Downside is MOT time getting it put in and out and the risk getting stopped by the police and getting your exhaust emissions checked!
