Nice lookin V35 wulf190, I got a in the cowl type OS elbow and I used a short OS flex pipe that is mounted to the firewall.Then I added an old Enya 90 4cycle muffler that exits threw the scale location on the cowl.Then I chopped the muffler to make it look more scale.That setup gives it a unique sound thats not too loud and looks scale.I guess you could do something similar if you had a Satio flex pipe..good luck on your first flights..Steve
