I modified my stock Muffler...but it was from the US-Model:
You have to cut the end pipe, then you find a spark arrestor who looks like i turbine. Put it away.
Also put away all stuff in the endpipe.
Then i took an old front header pipe from the DR350 ( i installed a new bigger pipe), cut it into a short part of the pipe where the bend is and welded it on the end of the muffler instead of the original pipe. You have to drill out the originaln, grind the hole until it is big enough and then insert the bigger pipe.
Now it sounds great, deeper...but not to loud. No Problems with police and technical checks every 2 years. I put some Picturs in the Tech-Faqs here.
for our english-speaking guests - english only. The place to discuss any DR350 specific technical / mechanical /repair / preparation questions you like, or answer others questions if you can.
