As downpipes seem very very hard to find and I have a set in bad condition and incomplete, I think I'll use the flanges and re-do the pipes.

 

I'll need help so I can get the 2 missing parts fabricated.

 

If anyone could be so kind and post a picture or a draw with the measurements and depth of the following part:

 

Japspeed, megan racing, etc. style downpipes 2.25" I believe

I have a pair of Specialty Z 5-bolt Super Split Down Pipes. I'll take pictures and measurements for you

 

Japspeed, megan racing, etc. style downpipes 2.25" I believe

 

Mmmm, that's interesting.

I was hoping that they were 2.5" as I have Japspeed testpipes. :no:

You mean testpipes? They are all 2.5" downpipes (except the latest "expansion" type which are 3"):

Thanks AndrewG, those are a bit different then mine, as one of the divorced pipes is a bit bigger on yours, but at least I have an Idea of the depth

Mmmm, that's interesting.

To be honest I haven't measure it yet, but I will later on. But I think they are 2.25"

2.25" inner diameter

Interesting, if you take a look at the SZ page for exhausts you can see that 2.25" is for NAs, and 2.5" (and then 3") for TTs:

These are outside diameter measurements.

Correct Andrew, I did mean test pipes.

I don't know why, but I always seem to get them the wrong way round.

2.25 it is

These are the tube dimensions for the 2.5" SZ supersplits. The inner bore dimension is a function of the tube wall thickness.
