Title: Milltek 3"DP onto 2.75" cat back?
Post by: mkviken on May 03, 2012, 06:41:00 pm
I've already got a non-res 2.75" milltek cat back but I'm thinking about fitting a down pipe and sports cat

the only one I've seen for the mk6 GTI is a 3", which i guess is compatible with their 'race' system straight out the box.


my exhaust is the suitcase type. does anyone know if they provide a 3"-2.75" reducer with the dowmpipe or if they do one with a smaller link pipe after the cat to fit my exhaust?

cheers

I used to have a Miltek TBE.  The DP was 3" & the cat back was 2.75" so the end of the DP / sports cat must be reduced to fit the 2.75"?

Not that I remember.  was 3" DP with built in sports cat straight onto 2.75" system.  Have you have a look on milteks website?

yeah it just says 3" for all TBE on the mk6 and the cat backs (non race type) are 2.75"


i would have assumed that the 3" down pipe would reduce down to 2.75" after the cat but non of the photos show this and i guess that would mean they would have to make 2 different types of link pipe or down pipe


all the mk6 systems seem to be 3" now and are phasing out the 2.75" with the suitcase silencer so i guess they're just going for 3" all the way through now?

From memory my last milltek downpipe was 3" and at the end of the connecting pipe it reduced to 2.75" and fitted straight to my car back milltek
