auspuff

As I know, there is no differece between both typs of exhausts.
May be inside, but better than using none.............

There are three different types:

2J2 (for 2J4)

48U (for 48T from 1984 to summer/autumn 1990)

3GW (for 48T since autumn 1990)

The best one is the 48U. But you need an 48T brake pedal, because it is a very little bit thicker than the 2J2.

What makes the 48U better?

It is a little bit bigger than the 2J2 (2J4) one. So it has more capacity.

[The 3GW one for only 17 KW has less flow rate than the 2J2 and 48U one.]

Also:
I would take 2J4 or 48T but not the last type 48T 3GW.
You can find out the difference by measuring the end-pipes inside diameter. It is only app.16mm.

Das macht mich stutzig. Ich habe hier einen 3GW liegen, der äußerlich exakt identisch ist, also auch beim Auslaßdurchmesser. Harald schreib ja mal was von den 16mm, ich hab sowas aber noch nie gesehen Gibt es den nun oder nicht?

@hakamate

Sorry, we are discussing the type 3GW with the named low diameter! Please wait for other answers about this.

Also nochmals: wer hat einen 3GW-Puff und ist in der Lage mal kurz den Auslaßdurchmesser zu prüfen? Oder hat jemand einen 16mm Auslaß und sagt uns bitte, was da drauf gestempelt ist?

Den Fred im andern Forum mit Haralds Messung find ich nimmer...

@Hakamate
I have asked again for the 3GW...

I will try to find my one today in the garage
then I can tell you what is writen on and the diameter

so , I found the exhaust
its a 3GW-14711
hi has a 23 mm outlet

Ich weiß nicht, ob Harald das Loch hinten meinte oder vielmehr den Durchgang innen.

Yes! This one will work. but you need the breakpedal of the 48T.
