Spring POLINI exhaust,
l 67 mm, Ø 12 mm, rubber cover
Springs attach the manifolds of many exhaust systems. The connection from the downpipe to the body is normally completed with springs, too. The SIP spring can be turned, it is easy to fit, and cushions very well. The annoying wirring noise that is sometimes confused for cylinder pinging is omitted.
