Best decat?

  1. Hi I'm in the market for a decat and just wondered if there were any real differences between brands. RST or Milltek.
    and what's the better size, 2.75 or 3".
    now I understand a larger bore is better for air flow etc. but when I will be putting it on my stock system it want really matter so any pros or cons really.

    Cheers, Kriss
     
  2. ya maybe need to think about what system ya want, if ya get a 2.75 decat and a 3" system its wasted, that would be my choice as i got system then decat
    my 2p worth :smile:
     
  3. The RST one sounds great , standard exhaust or not .
     
  4. If these are so difficult to fit how do people get away with Mots!?
     
  5. my mot tester fitted mine, so change it every mot i think not!
    you can put a inline one in where the mod box would be for passing mot 1_90_1.jpg
     
  6. Is the stock system 2.5"? As I say it will be mated with the stock system so size isn't really an issue. I was just curious if either were louder/ better gains?
