Hi,

I recently removed the muffler on my OM 616 turbo which comes with the 617 turbo muffler and put a straight through pipe instead. I noticed an immediate increase in the throttle response and the engine pulled much better at higher revs than before, anyone else tried out this mod? If so would love to hear about your experience. Also if there is a chance of any kind of damage, please put forward your theory as it is quite important to know the cons of doing this.

The noise level didnt go up that much, only some rumble but still within limits and quite tolerable as most exhaust impulses are taken up by the turbo itself.
