Reply To: How to become SERIOUS SOUND on a 701


You may as well go all the way and go for a cheap AliExpress decat pipe + muffler (replica or not) that as close to no db killer; the ones for the duke 690 should fit (tbc) but in no way you will be street legalĀ (from your license plate I assume you are driving in Germany but this could be a wrong assumption).

Changing just the muffler only adds a bit of whomph at mid/high rev but imo is more pure aesthetics rather than loud noise (euro 4…)
