We've been working with different lengths of the pipe before the X to produce better sound and to better promote the scavenging effect. Our main goal right now is to try and mellow out the titanium a little; while the camera does amplify the tinniness of the exhaust a bit, we won't lie, that exhaust is pretty damn loud right now lol
