Stainless Steel Tuned Pipe for engines from 45 to 80 cc

This tuned pipe is precision engineered from thin wall stainless steel, laser welded and highly polished. The geometry is exactly that of the Seyer tuned pipe but it is of indescribably better quality. Before Seyer ceased business we bought the complete set of tools and dies so we can exactly reproduce these pipes.
For example, with this tuned pipe a ZG 62SL turns the 24x10" Super Silence CF two blade propeller at 7,100 RPM with a 17 cm header length. The tuning length for other propeller speeds can be taken from the power curves from the ZG 45, 62 and 80 on the respective catalogue pages. Due to the reflector cone, the tuning effect produces a smooth increase in power, there is no sudden jump in RPM and the power increase is spread over a wider rpm range.
