External bore measurements for milltek decat
« on: 10 May 2011, 02:09 »
I know its for a Tdi but some of you petrol guzzlers might know.
Im trying to find a reducer to fit a Milltek tdi decat to my standard system but cant seem to find out which reducer to buy! Does anyone know what the External measurements are of the two pipes im joining? All ive seen is that its milltek 2.5" and standard is 2.25" but dont know if thats internal or external  :undecided:

Cheers for the replies  :smiley:

I ordered one off ebay in the end with the following measurements:

External Diameters approx.  - 68mm - 64mm - 60.5mm

Large end I.D.  65mm, small end 57mm

Overall Length approx. 130mm.

Looks like it is too small for what i want :(

Im like a kid on sweets at christmas!  :laugh:
Just checked you link out (thanks for it btw) but how does a "2.5 sleeve join 2.5" to a 2.25"? Surely one end it way too big  :huh:

Jetex website isnt exactly great at higlighting that, the info makes it look like a normal straight sleeve with kink bit!
And you say that fits over both ends perfectly?

Fitted lovely - the clamps then hold it place  :smiley:  I ended up with a longer sleeve as they didn't have that particular in stock and I needed it next day!  So ended up having to cut approx 1" off the Milltek downpipe

Thought I had pics of it but can't find them now  :undecided:

The easier option would have been to buy the THS downpipe as that comes with adaptors  :smiley:  Didn't know that myself until after I bought the Milltek  :sad:
