Heavy duty threaded exhaust flange kit for use on GX270 engines. This is an un welded DIY kit, Great for custom exhaust setups on generators, go karts, mini bikes, or garden equipment. Flange is CNC cut from heavy 1/4" STAINLESS STEEL plate to prevent warping, outlet pipe is 1" NPT pipe thread that matches exhaust port perfectly for maximum flow. Length of outlet pipe piece is 2". Comes complete with Gasket + stainless steel mounting hardware for a quality installation. This kit requires welding. If you do not have access to a welder most muffler shops are able to do this for you. If you prefer, I also offer these threaded adaptors fully welded. Other adaptor kits and fully welded adaptors are available for Predator 79cc, 212cc, 301cc, 670cc, GX, and Tecumseh motors in my amazon store.
