De-cat advice

[Spaceman]

Hi guys bought a ninja backbox from a guy, he also has the de-cat pipe that hes willing to fling into the deal for 50 squid, so sound good. Am worried tho how this will affect my car will it still be legal? and will my car run smooth with it and will there be a noticable performance diff? or should i just leave it and get PPP in a few months?

Greig,

IMHO (opinion)

I had a Blitz Nur sec R on my car. it was a decat. its not legal. the car ran like a jamjar filled with wasps.

Had i got it mapped with the new illegal decat on it.......it would have added maybe 10%power and driven smoothly.

YOUR CASE-

Pro's- cheap. you want it. youll get slightly more performance and open yourself up for the mods ahead. you could buy this then get a remap/fuel pump and IC hose (this will give you PPP power without spending 2k)

Against- i think.......a maps needed. whys he selling it? its illegal

hope this helps

NB. most people have decats and never get checked by VOSE.

Spaceman,

I noticed a big difference with my car just de-catted then got it mapped and so far it has 326bhp so there was a noticeable difference to mine I would recommend it against ppp, it also sounds the great....

If your car is a WRX and not an STI the you will be fine.

You should notice a nice little boost in performance

On the other hand if its an STI, then dont do it unless your going to re map it straight away.

Fitting the de cat downpipe plays havoc with the car and can result in engine damage.

is it the de-catted downpipe he is throwing in or is it just the de-catted un-resonated centre section????

if it is just the centre and back box then all you will notice is a slight noise increase and will not require a remap.

does a UK 2ooo turbo need a remap instantly after fitting a decat D/P??

No,

No non STI cars need to be re maped, it is a bonus to do so but not a neccessity like the STI's

ok thats good news then

Mines came in to the country with a stainless on it anyway. But i took the cats out so its now, literaly, a straight through!!!!!!

I have one silencer left on it and its sounds deep and really loud.

I never got mines re-maped. Was told it wouldnt need it. Mines is an STI v2 but was told to reset my ecu and it would do the rest. That was 2 years ago now and NEVER had ANY bother. It runs about 300bhp after a few other minor mods.
