Review on Flexible Muffler 🔧 Engine by Niome Viper by Mark Hart

WARNING WARNING. If you have an oval shaped exhaust port better plan to reshape the muffler pipe end where they join or my neat mine got started from overheating and I couldn't otherwise stop it and then tighten the boot backwards. Carburettor it's a good thing I had the filter removed when I almost lost my engine and I also found that the flex pipe was under the flange which traps the heat so unless you plan on a little reshape and trim, pull out flex pipe, take out and connect, so that the flex pipe slides on the link pipe, do not use this exhaust system.
