    Im looking into getting an exhaust to meet my 3" downpipe with sports cat.
    I have been given a reasonable quote for a 3" cat back system to meet my downpipe. That would mean that the exhaust is 3" turbo back.
    Is that a bit overkill? I know as Bill @ Badger5 says "Its all about the flow" but I know the Milltek is 2.75 inch.

    If the 3" is no good, it seems silly to fit a Milltek as that would mean my system is 3", 2.5" (the tapered bit on the downpipe that usually meets the standard exhaust) then 2.75".

    I also dont want it to sound like a 1.2 corsa, I just want to firstly meet the requirements of stage2, and seconly have a bit " grunt " under acceleration.


    Any help appreciated as always!

    Look at Gops build thread... Bill made him a custom 3" exhaust to go with his Miltek back box...

    Thanks for the quick reply, tufty to the rescue as always!

    I have had a look at that thread, the system looks aweosme!

    I think im just going to go for the 3", with milltek special style tips.
    As long as 3" isnt too big, but as I understand its the turbo that supplies the back pressure on a turbo's car?
