Hi shouter :wink:

The cat will most prob fail the MOT (no personal experience but others suggest this.) and you may need to re install to pass :?:

The DV is a piece of cake to install - even managed to do it myself a while ago (and im a keyboard pusher)

Unsure of the grills as never attempted this but im sure someone will reply soon.

Good luck with the mods - keep us informed :wink:

so am I right in thinking that it should pass as long as the downpipe cat is still in place?

The debate goes on, some say it will pass with none others say it will fail.

If you have ppp the centre cat is removed anyway

Depends on who mot's the car :wink:

I would say as long as you A Cat in place, you'll be alright. I.e you will need at least one.

I think the debate over wether you need a cat or not comes down to emissions.I was under the impression that a cat itself was not a requirement but modern cars will fail the emmisions test without one. If you can make your car pass the emissions test and leave the cat off then that would be fine.

Hi mate

As it stands a Fully decatted car will (unless its been remapped) generally fail an MOT. I had a Full Decat and fitted just the centre pipe (small cat) and it took the tester 4 times to get the car to pass. Basically the Cat had to be warmed up before it would pass. The D/pipe cat is much bigger and you can generally get a car to pass the MOT with just this one fitted.

As for fitting different ECU's - Be careful mate ! Remember the Jap ECU's are tuned for higher RON Fuel. On top of this there may be differences in Turbo, Injector sizes etc, larger diameter exhausts etc? You may well need to carry out some Modifications to your own Scoob before attempting to fit an ECU that will give you more power. You have a MY98 car and as far as i know there are no known remaps for yours Best bet I would suggest is to either buy a complete replacement aftermarket ECU (the Apexi one if well regarded) or have a piggy back chip fitted, something like the Dastek UniChip is a good one. Just make sure you employ a good Mapper

Hope this helps ?
