Installation instructions

A LeoVince Silencer is designed for particularly easy installation and manufactured in a proven SLIP-ON construction. The original silencer is first loosened. Depending on the version, the supplied connection pipe is then inserted to optimally adapt the angle and alignment to the vehicle. Then the silencer is put on precisely, attached to the series mounting points and secured with the supplied springs.

After the exact alignment in the desired position, clamps and screws are tightened evenly. A short functional test while stationary and the tightening of the connections after the first few kilometers ensure a permanently firm seat. The precise construction noticeably facilitates the conversion.
