Full race prepared GX160 modified exhaust. This exhaust has been taken a step further than the ordinary debaffling, the manifold has been fully ported and polished, the baffle plate has been machined on the milling machine with a 16mm reamer and then fully ported to match the manifold. These exhausts are for modified but stock appearing classes. 0.5HP increase in power over the normal debaffled exhaust.
