Exhaust Pipe for G Wagon 461.401 - German Diesel - 10-21-2018

Hi Guys,

i am new here and not sure if it is right that i drop this post here in this topic.

I want to change the engine in my G wagon, from an om 602 to a OM 606 Turbo diesel (just with max. 180 HP). So far so good. 
The engine is ready and in my Workshop, the engine run's well ?.

My original Exhaust Pipe is broken (30 years old), i have to build a new one. The pipe itself is ready, but i need a sound absorber to get under 87 (dba).

In the next post, i attech some pictures from, what i have already done.


Kind regards from Germany, Steffen

The exhaust gets through a 60 mm pipe in the end of the sound aborber, my opinon is that the exhaust have to get through some stainless steel wool in front and get through the sheet with the many holes on the other side.

Well just my opinion... turbodiesels go very well with only a mufler at the end of a long pipe. For perceived noise.
But if u want to measure 87 decibels at the pipe that silencer should do. Anyway it will restrict a lot. U could have it done wider.
