    Vectra inlet installed

    Hello All:

    I relieved Vectra inlet today , I just installed it.

    Fitting was not easy

    Yesterday I made derestriction - yes the car became much noisy and much responsive.

    now all done
    K&N filter
    NGK spark plugs
    Derestriction
    Vectra inlet.

    Any other thing to do?
    Is there a way to reduce the noise?

    Thanks All

    Try Changing the muffler. Muffler's design/size has a lot to do with the noise or sound of the engine especailly if you rev the gas.

    good luck!

    muffler? you mean exhaust?

    there's not much can be done about the increase in noise, but TBH after a few times driving it you won't notice it as much! Whatever exhaust you have will affect the engine note as well, but if you've not changed the exhaust from standard then it will purely be down to the derestriction anyway.

    Derestriction = Slightly more noise = slightly more power

    Take the noise away and you're back to where you started. You can't really have the increase in performance and the lack of noise - its one of the other - standard or derestricted. . The restriction is afterall a noise restriction at the end of the day (amongst other things)

    Just forget about it - unless of course theres an air leak somewhere and the noise is air escaping... if everything is correct though then I would suggest you just forget about it - you'll get used to it and start to enjoy it.

    If you think that's loud you should hear my car! haha

    Totally agree your car shouldnt be on the road! Well at least it shouldnt be driven at 7:30 in the morning revving the hell out of it, and waking up pretty much all of the hotel in Milton Keynes!

    and I wonder why we the general public have a bad image of us

    Thanks all for reply.

    I could not get the affect of each mod separately.

    But I think filter and sparks made a noticeable affect.

    De-restriction and inlet increased the noise. may be little better response.

    has any one could measure the affect on each mod?
