I've decided that the hassle of getting an MOT with a decat is not worth it, so I've had a 3" Milltek sports-cat centre section fitted in place of the resonated centre section. Downpipe still has no cat.

Car sailed through MOT

I have been advised that driving the newly re-catted car with its current decat map is OK as long as I don't drive it hard, or for too long...but as the new turbo I'm waiting on keeps getting delayed I'm worried about the prospect of causing damage.

Does anyone know what the issues are with driving a re-catted car? What should I avoid doing? My best guess is that I'll be driving it like this for 3 or 4 weeks.

 

Anyone? Would like to know what to avoid while driving with the cat fitted before the remap...or, even, if I really shouldn't be driving it!!

 

If you are worried drive off boost

 

had my car mapped twice wi a sports cat on but failed mot with it so put ome one back on for 6 months while i sent my sport cat back for cheaking (nothing wrong they say) and had no problems in that time and i still continued to batter it when i could and could feel restriction...anyway dont know if this helps or not
this was wi hks headers, vf35, sti cooler,etc etc on a basic 2000uk

 

I suspect it will be fine Tim but you are welcome to pop to Surrey Rolling Road on wednesday or thursday this week and I'll plug the laptop in and put detcans on it and you can drive it up and down the road so I can check

 

oh and concern is engine not cat.. fuelling for cat will be okay.

No nasties on knocklink, so think it's ok, but thanks Simon...I might just do that

 

no worries
