排氣管出口長度設計與當時送審設計有出入
During the end of the last round of qualifying IFMAR received a protest against the Sirio 2611 muffler.
The Protest was not accepted due to the wording in the Protest.
However, based on a discussion at the 1/10th Section meeting, held on Thursday evening the IFMAR committee has decided that from Friday 15th, on the pipe 2611 in its new version/layout is not allowed.
There are 2 versions in the market from the 2611 pipe, but IFMAR has no information about a changed in the design of this muffler and will only accept the old version.
The results from qualifying will remain as it is.
The old version has a normal tailpipe of about 16mm with a striaght design.
The new muffler design has a shorter tailpipe of abut 12mm and a thicker wall with a conical design.
