I had a great idea. After having it sitting here since late June, I finally opened the TTI box to see what muffler they gave me. It is a Dynomax Super Turbo #17733.
Is this a drone monster? I want quiet. The posts above say a quiet flow or an ultra flow.
Turbo mufflers just don’t sound good on inline motors IMO. The Ultraflo is for max performance, if you want quiet go quiet Flo or another large case muffler.
