Hey, tried searching this for a few mins...but can't seem to find the stock s5 turbo outlet size. I saw a few discussing bnr hybrids...but not stock. I'm trying to get the reducer's for a custom fmic setup. I have 2.5" pipe, and an IC with 3" inlet's and outlets's...so I'm looking at (2) 3"- 2.5" reducers for that, but I need to know what the stock outlet size on the turbo is, to see if I can find a reducer to go from the 2.5" piping to the outlet...so...what's the diameter of that outlet? Also, anybody that has the higgi TB elbow...is that a 3" opening or something else? I'll need a reducer for that as well..unless it's 2.5". Anyway, shed some light on this for me.

I would suggest a tape measure. You might get a faster answer that way.

I don't have the car here to measure it and I was just trying to get #'s since it's the stock turbo...I'm sure somebody here knows it. This way I can go ahead and order the couplers I need. If I had the parts/car here I would measure them....

The stock turbo compressor outlet is 50mm (~2"). The GReddy/Higgi TB adaptor is 70mm (~2.75").

Hmmm if the higgie elbow is ~2.75" would I be better off stretching a 2.5" coupler over it..or going with a 3" and trying to tighten it down more? I ask this because I don't remember seeing too many 3" to 2.75" reducers.

either way will work but i would suggest the 3" and tighten down but i think that the 2.5 could be too small.

or, buy the right size

they definitely make 3.0-2.75 ID reducers. and the 3in, you probably wouldnt be able to tighten it down enough to get a good seal between the elbow and the coupler and risk the chance of the coupler popping off.
