SUITABLE FOR ZENOAH G260PUM, G290PUM, G300PUM, G320PUM,  QD, CY, RCMK & OTHER 26 - 30.5cc MARINE GAS ENGINE
With more Zenoahs coming out in 29cc, 30cc & now 32cc - don't you feel that 7/8" headers very constricting & too restrictive as they were initially designed for 23cc engines and widely adopted by the 26cc. Time to up the ante and use 1" headers and Hot Pipes designed for 29cc, 3 0cc & 32cc  marine engines in mind. Set it up properly and it will add more than 1.5HP to your gas engine.
Total length of pipe 13.75" ( 350mm)
Widest Width 3.0" (75mm)
Comes with adjustable stinger. Use a Gas Tacho ( available in my eBay Store) to determine the correct header length and stinger length then cut off the excess length (use a portable grinder to cut them off as they are stainless steel) Cut the internal length equal to the straight portion of the pipe do not protrude into the funnel portion. Start with the header length - total length from edge of piston to the maximum wide of tune pipe at the rear of tune pipe - 11.75" of airflow distance. For stinger start with 2" length.
