Daverse 175 Posted September 6, 2011 Report Share Posted September 6, 2011 no, only cars before 92 don't need cats to pass not Link to post Share on other sites
Ben Seabrook 4 Posted September 6, 2011 Report Share Posted September 6, 2011 they can do mate yes but depends on how healthy the engine is, my last two have gone through the MOT without a decat Link to post Share on other sites
craggsy 91 Posted September 6, 2011 Report Share Posted September 6, 2011 Legally they shouldnt pass the MOT without a cat on as someone said above.But they do pass as Benjamina says Link to post Share on other sites
paceo 22 Posted September 6, 2011 Author Report Share Posted September 6, 2011 cool is it illegal to use one though??also is there much of a performance gain or not??1992 car i have so its an early one. Link to post Share on other sites
craggsy 91 Posted September 6, 2011 Report Share Posted September 6, 2011 Yes it is illegal to run a decat. If VOSA pull you in for a road side test and see you havent got one they WILL have your arse.FI benefits greatly with out the cat in place....not 100% sure about standard cars Link to post Share on other sites
Ben Seabrook 4 Posted September 6, 2011 Report Share Posted September 6, 2011 as above FI cars its well worth having one, am sure you will get a small benefit on a n/a car as its bound to allow the exhaust gases to escape quicker and therefore aid efficency but I am not sure if you would notice the difference ?

Vw_owner 1 Posted September 6, 2011 Report Share Posted September 6, 2011 i recently had my exhaust replaced for a milltek catback and i was told i needed a decat pipe for it fit becuase i didnt have a standard cat i basicaly had a subaru style 4" drain pipe exhaust which was loud as fxxxx so i wanted it replaced with a milltek anyway i got it all fitted and the results were sick! i mean real sick! throtle response is tightened up and real responsive and the car felt completly new! smooth and quicker! weather this is down to my previous exhaust not being correct or the cat? i dont know but i dont regret haveing a milltek decat setup! btw i live in the channel islands and we dont have mot or emmisions tests Link to post Share on other sites
