<![CDATA[DT125R 1988 exhaust dep Will be compatbile with Dt125RE Dep epansion chamber?]]>Hello.

Im thinking of getting the dep exhaust for my bike now that im finishing the restoration, but i like the old dt125r 1988 exhuast dep has:

But idk if it will be compatible with the normal dt125re and its dep exhuast chamber, so far they look very similar:

Does anyone know if they are compatible? I like the retro look of the old exhaust silencer.

If not, im thinking of getting this exhaust, its a spanish artisanal exhaust made by TPR a local guy, they seem very good:

Here in the UK, they typically rust before too long. I always cleaned mine when putting it away and it held up well.

The one in the photo looks similar that it's mild-steel, so you'll want to get that painted before you fit it.

I run a Romeu Henriques pipe on my DTRE. I've had it since 2011 and there isn't a blemish on it as he made mine out of Stainless. It's also not cracked in that time either.

I went for underslung due to my setup, but he does wrap arounds also.

I guess i'll have to go with the newer one, as im not skilled enough to fabricate new mounting points.

As for the other exhaust, what do you think of it? The new DEP runs me around 500 euro and this artisanal one runs me for 280. Pretty juicy deal tbh.

If not i was considering getting a romeu henriques pipe, but not sure about it. This 280 euro TPR exhaust seems pretty good.

Thank you as always for being so fast answering man.

Whilst the engine is basically identical, so the actually performance/shape of the pipe won't be affected by the later design, the frame mounting points are different.

It's worth noting, the very early DTR's ran a 3BN cylinder, so there are subtle differences in actual engine specifications. Can you confirm that you're running a 3BN cylinder? Or the revised 3MB cylinder?

I can't remember whether or not the fact the mounting points differ was a deal breaker or not, or in other words, did it cause it to foul the frame.

My gut instinct is no and you should be okay, if you can make a couple of brackets.

I've done something similar with my Aprilia ETX, where I have put a full arrow system off of the SX models. The engine is the same, but I've had to fabricate up some brackets to get it to fit.
