Exhaust Header Gasket Kit To Suit Honda CB250/400T, CB250/400N Superdream Range of Classic Motorcycles

Two types of exhaust gasket were specified by Honda for these models- by far the best are the copper "crush" type.  These allow a greater range of adjustment of the various parts of the exhaust system- headers, balancer box and silencers- and still provide an effective seal.

As such we only recommend and fit this type- they are sized to fit the exhaust ports exactly and will seal both the OEM Honda and pattern headers available.

The kit is a set of 2 copper crush washers- enough to seal one complete exhaust system.  Honda used the same gaskets on many bikes- just buy multiples of this kit for the 4 cylinder models.
