   Doesn't this mean it fails its MOT? or do you have to fit a cat under the car lyk the pre X reg's? Can you decat both Mk1 & Mk2? just a bit confused at the moment lol. Cheers

   right 98bhp vtrs would fail mot if you put a manifold on it as it de cats it unless you get a manifold with a sports cat
   
   the earlyier vtrs no it wouldnt providing you still have the cat there

   you would need the middle section off a mk1 if you was to do that
   
   im not sure what effect having a lamba sensor in a sleave would pass emissions test though as it should be plugged in just after the cat

   2nd lambda doesnt affect emissions. it checks the cat is working.

    What would be the best manifold for my Mk1 Silvertop 90bhp VTR?
    Heard so many things from so many diff people!
    
    My current mods are:
    Pipercross Viper
    S/S Decat
    Remus centre pipe
    S/S Magnex Backbox
    
    Im pretty sure a 4-1 would be best as I find my vtr doesnt pick up all the time till about 3-4000 but Im not certain....4-2-1 may be better!
    
    Let me know what you thinks best peeps!! Thanking you!
