Hey all. I just picked up a "new" 2021 Urban and wondering if anyone has run with just the factory headers and the cat NO muffler...? I have had a couple of 1150GS' and just place a 4" shorty pipe to divert the exhaust and it ran and sounded great- No excessive noise at all and minus 20 lbs of muffler...

There are a few threads on the Exhaust section that also cover this area. Here are a few links to get you started.
