Hi there, Iím a new MP3 convert after recently purchasing a 2011 MP3 Yourban 300. I got a good deal and the bike is running well with 15,000km on the clock.
The one problem is that there is a good deal of corrosion on the muffler and suspension springs. I picked up a complete second hand original piaggio yourban exhaust assembly on ebay which is in really good condition, I think from 2017/2018.
This new muffler is euro 4 compliant whereas my yourban is euro 3. My question is can I install the euro 4 muffler without any problems? I presume that the catalytic converter in the new muffler is different to the original (2011 one). I intend to use the original exhaust manifold/lambda sensor so will only change the muffler. I would really be grateful of anyone can share their expertise here!
