    Thumbs Up Back box and pre cat and now what?

    I have got a miltek back box on my car and have a Pre Cat pipe to be fitted to the car and now i want to buy the rest to make the full system but do i need to buy all these new bits as i have been on to Courtenay Sport and had look on there site at full systems and there was this list

    1.Turbo pipe (already got)
    2.hi flow cat assembly
    3.centre silencer
    4.over axle pipe
    5.rear silencer(already got)

    do i need to buy it all or just the hi flow assembly to make the full system??

    Cheers

    you should just need the bits in the middle if you already have the front and rear parts.

    i would have thought you would need,
    2.hi flow cat assembly
    3.centre silencer
    4.over axle pipe

    to go with what you already have to make up the full system.

    No, silencer will be less restrictive, they'll be a larger pipe diameter and stainless steel so no rust

    Milltek system is a bigger bore than the OE one, so I am not sure how you have managed to mate them together???

    Milltek cat back and sports cat would be a nice buy, get it bought, and I will give you a hand to fit it, when it warms up!!
