Hi everyone. I hope someone could help me in modifying my stock muffler for motorcycle Suzuki Freewind. It is 650cc one cylinder enduro bike.
I want to make it louder, but not too loud, becouse it is almoust silent
This is pic of inside pipes. Should I drill some holes, shorten some of them or change outgoing resonator pipe with some larger diametar (now it is about 27mm)?
You can see in this view from the "engine side", the middle thinner one is resonator pipe.
