I just replaced my Arrow exhaust that was damaged after tucking the front when racing with a Ti-Force exhuast. When installing the exhaust, the directions mention a gasket or exhaust connector that mates the s-tube with the exhaust manifold (next to set valve). Problem is that when I got my race bike I didn't have stock exhaust, and Ti-Force pipe is sized to connect to this small connecting piece. Has anyone replaced their stock exhaust remember seeing such a small part? From the tech manual diagram it looks about two inches long. I need to find such a part of figure out how to seal the gap as my ti-force connection is a couple mm too large.
